Do we perceive the weight of our body parts and the weight of objects differently?
According to Newton’s law, weight is given by the product of its mass and gravity. How does the brain determine the weight of objects and body parts?
Does the combination of psychedelics and meditation enhance mystical experiences?
Researchers assessed whether combining psychedelics with meditation increases mindfulness, compassion, insight, and mystical-type transcendence to a higher degree than meditation with a placebo.

Research on Alzheimer's disease wins Prémio BIAL de Medicina Clínica 2024
Neuroradiologist and researcher Tiago Gil Oliveira was the winner of the Prémio BIAL de Medicina Clínica 2024, with the work ‘Uncovering the mysteries of brain regional susceptibility to neurodegeneration in Alzheimer's disease: from neuropathology to brain magnetic resonance imaging’, which identifies the brain regions differentially affected by Alzheimer's disease, contributing to a more accurate and earlier diagnosis of what is the most prevalent neurodegenerative pathology in Portugal and worldwide.
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.
