How does our brain organize past memories?

Episodic memory allows us to mentally relive moments from the past, retrieving details such as what happened, where, and when. However, the way we recall these events can vary, highlighting different aspects of the experience. Studies indicate that cued recollection simultaneously activates two essential brain networks: the DMN (Default Mode Network) and the FPCN (Frontoparietal Control Network). An investigation led by Matteo Frisoni analysed whether different memory dimensions – details of objects and characters, spatial layouts, temporal sequences, and verbal dialogues – are processed in specialized sub-regions within these networks and whether this differentiation influences recall performance. The results showed that the FPCN exhibited common activation for all memory dimensions, while the DMN revealed more pronounced specialization, especially in its posterior regions. Additionally, it was found that greater functional specificity within these networks was associated with better memory performance. The research also revealed an asymmetry in the DMN, with greater activation in the left hemisphere for all dimensions except the temporal, while the FPCN maintained balanced activation between hemispheres. This study offers a new perspective on how the brain organizes and optimizes our ability to recall past experiences. This study was supported by the BIAL Foundation, in the scope of the research project 384/20 - Schema-based temporal memory in parietal cortex (SCHETEMP), and published in the journal NeuroImage, in the article Specialization for different memory dimensions in brain activity evoked by cued recollection - ScienceDirect.

Why do some people remember their dreams and others don't?

Dreams are like windows into the mind, reflecting daily memories, beliefs, and concerns, while playing an essential role in learning, memory consolidation, and even our mental and physical health. Although almost everyone dreams, the ability to recall these experiences varies greatly from person to person. Research led by Giulio Bernardi sought to better understand this phenomenon by analysing the factors that influence dream recall. To do this, the team used a multimodal database that collected dream reports, personal characteristics, and cognitive, psychometric, and neurophysiological measures. The results point to three main factors that determine whether a person wakes up with the memory of the dream experience: attitude towards dreams, tendency to mind-wander, and sleep patterns. Additionally, the ability to recall dream details depends on resistance to interference and age. Interestingly, similar sleep patterns seem to favour both dreams with content and so-called "white dreams" - those we know we had, but whose content escapes us. This suggests that white dreams are real experiences, whose memories simply disappear upon waking. This study reinforces the idea that dreams are shaped by individual and momentary factors, opening new perspectives to understand their connection with memory and the human mind. This study was supported by the BIAL Foundation, in the scope of the research project 91/20 - Mentation report analysis across distinct states of consciousness: A linguistic approach, and published in the journal Communications Psychology - Nature, in the article The individual determinants of morning dream recall | Communications Psychology.

Can meditation change the way we face death?

The brain is constantly creating and updating models of reality, anticipating future events and adjusting to minimize surprises. Although this mechanism is essential for our adaptation, it can also lead to an unsettling awareness of mortality. To avoid this discomfort, the brain has developed automatic ways to distance death, attributing it to the "other" rather than oneself. A team led by Aviva Berkovich-Ohana investigated whether meditation could reduce this natural tendency to deny death. The study revealed that experienced meditators react differently compared to novices: instead of rejecting the idea of their own mortality, they seem to accept it more naturally. Thus, the results provide evidence that meditation can transform the way the brain processes death, shifting from denial to acceptance. Furthermore, this change was associated with greater well-being and advanced states of self-transcendence. This suggests that integrating meditation into clinical contexts could be a promising approach to dealing with the fear of death, complementing psychological and pharmacological therapies that more radically affect self-perception. This study was published in the journal Neuroscience of Consciousness, in the article Training the embodied self in its impermanence: Meditators evidence neurophysiological markers of death acceptance, as part of the research project 191/20 - Understanding the brain mechanisms of death-denial for fostering mindfulness-based existential resilience, supported by the BIAL Foundation.

Did you know that some studies supported by the BIAL Foundation are among the most cited in the world?

The research funded by this Foundation has generated innovative discoveries with a significant impact on science. According to the most recent data, covering November and December 2024, 17 articles resulting from this support are part of the Highly Cited Papers group, meaning they rank among the top 1% most cited in their academic field and year of publication, according to the Essential Science Indicators (ESI). Among them, a study published in Science Advances stands out, exploring the dynamic patterns of the brain associated with consciousness, helping to better understand states such as coma and sleep. Another widely cited study, published in PLoS ONE, investigates the challenges of meditation and its psychological effects, a topic increasingly relevant in contemporary Western society. A study published in the journal Cortex explores whether the human brain, particularly the left frontal lobe, may act as a filter to suppress innate psi abilities, such as psychokinesis. An article in Biological Psychiatry outlines an essential roadmap on interoception – the perception of the body's internal signals – and its connection to well-being. Other widely cited articles analyze altered states of consciousness (such as meditation, hypnosis, and psychedelic experiences), the brain mechanisms of insomnia, and even the effects of COVID-19 on cognition. With hundreds of citations and growing impact, these studies reinforce the importance of the BIAL Foundation in understanding the human mind, paving the way for new scientific discoveries.

What happens in the brain when we say "No"?

Negation plays an important role in language, changing the meaning of sentences and the focus of our attention. Recent studies suggest that understanding non-action sentences, such as "She did not write the letter", involves brain areas responsible for movement control. In this context, Alessio Avenanti and collaborators investigated how reading affirmative and negative action and attention sentences affects inhibitory and facilitatory mechanisms in the primary motor cortex (M1), which controls movements. Using a technique called transcranial magnetic stimulation (TMS), they discovered that negated action sentences (like "did not write") decrease activity in the brain's motor areas, blocking action. However, non-action sentences, such as "She was not attentive", do not have this effect. Negated action sentences also reduce the activity of inhibitory circuits in the brain, regulated by the neurotransmitter GABAA, but do not affect circuits that facilitate brain activity. These findings help us better understand how the brain processes language and how this is connected to the movements we perform. This study was supported by the BIAL Foundation, in the scope of the research project 304/22 - Boosting and hindering action imitation by modulating spike-timing dependent plasticity, and published in the journal Brain and Language, in the article Exploring the impact of sentential negation on inhibitory motor networks: Insights from paired-pulse TMS.

Did you know that the human brain can study itself?

It seems like a paradox, but it's true! The brain, responsible for our consciousness and perception, has the unique ability to study itself. But how can an organ analyze itself? How can the brain serve as both the subject and the tool of its study? A recent review, led by Simone Battaglia, delved into these questions, combining philosophical and neuroscientific perspectives. In trying to understand itself, the brain faces a unique dilemma: how can a complex system analyze its functions without an external reference point? This dilemma is compared to the philosophical concept of "self-reference", where a system must define and understand itself from within. Another key issue is the dichotomy between scientific objectivity and the subjectivity of conscious experience. The study suggests that a complete understanding of the brain and mind requires an approach that integrates both aspects. Effectively, scientists combine advanced brain imaging techniques, such as MRI, which studies the brain at structural and functional levels, with introspection, the process of reflecting on thoughts and experiences. These complementary approaches allow for a deeper understanding of the mechanisms underlying consciousness and perception. Studying how the brain generates different states of consciousness can help identify signs of disorders such as depression or schizophrenia, and new ways to treat post-traumatic stress, for example. There is still much to discover, but these studies could pave the way for new insights into understanding and addressing the complexities of the human mind. This review was published in the scientific journal Physics of Life Reviews, in the article The paradox of the self-studying brain as part of the research project 235/22 - SPARKS: Driving associative plasticity in the cortically blind brain to promote recovery of visual awareness to promote recovery of visual awareness, supported by the BIAL Foundation.

How does the brain learn from rewards and punishments?

Our brains select the most important information and focus on it. To make decisions, they evaluate whether each stimulus is positive or negative. Positive stimuli encourage approach, while negative ones lead to avoidance, aiding in survival. The nucleus accumbens (NAc) plays a central role in this process, but the functioning of its neurons is not yet fully understood. The team led by Carina Soares-Cunha studied the D1 and D2 neurons in the NAc to understand how they distinguish stimuli and influence learning. Using advanced imaging in mice, they observed that associative learning (when a stimulus is associated with a reward or punishment), both types of neurons are activated and work together, but in different ways. However, when associations change, such as when a negative stimulus no longer has an unpleasant consequence, D2 neurons are essential for extinguishing that aversive association. Since difficulties in modifying negative associations are linked to anxiety and post-traumatic stress disorder, better understanding the function of D2 neurons may help develop new treatments. This study was published in the scientific journal Nature Communications, in the article Dynamic representation of appetitive and aversive stimuli in nucleus accumbens shell D1- and D2-medium spiny neurons, as part of research project 175/20 - The role of nucleus accumbens in the perception of natural rewards, supported by the BIAL Foundation.

How does heart rate variability shape emotional brain networks?

Brain connectivity and autonomic function are closely related to emotional regulation, interoception, and autonomic stability. The Default Mode Network (DMN), associated with self-referential and emotional processes, and the insula, which plays a crucial role in interoception, emotional regulation, and autonomic control, are functionally interconnected. These two components often activate together during certain mental processes, suggesting a fundamental interaction between cognitive and emotional functions. To deepen the understanding of this interaction, a study led by Joana Coutinho investigated the functional connectivity between the insula and the DMN, also exploring its relationship with heart rate variability (HRV), an important marker of autonomic regulation. HRV is a measure of the autonomic nervous system's ability to respond to stress and maintain emotional stability, making it a relevant indicator for studying emotional regulation. The results showed a significant positive correlation between the functional connectivity of the insula and DMN, but no direct relationship was observed between this connectivity and HRV. This finding suggests that the interaction between brain connectivity and autonomic regulation is more complex than initially thought and may require more sophisticated models to be fully understood. Therefore, these results highlight the importance of future studies for a more detailed understanding of the brain circuits involved in modulating heart activity, which could lead to the development of more effective therapeutic strategies, especially for clinical populations with alterations in these processes. This study was supported by the BIAL Foundation, in the scope of the research project 87/12 - Neurobiological correlates of empathy in couples: A study of central and peripheral measures, and published in Brain Sciences, in the article Examining Insula – Default Mode Network Functional Connectivity and Its Relationship with Heart Rate Variability.
