Details
The symposium addresses the pivotal role of astrocytes play alongside neurons in shaping brain activity and complex behaviors. Astrocyte-neuron signaling represents a cutting-edge frontier in neuroscience, offering new insights into brain function that extend beyond traditional neuron-focused research. Astrocytes, a type of glial cell once considered merely supportive, are now recognized as active participants in the brain’s signaling processes. They modulate synaptic transmission, regulate blood flow, and play critical roles in neurovascular coupling and metabolic support to neurons. This symposium highlights cutting-edge discoveries by experts in the field revealing how astrocytes contribute also to higher brain functions, such as memory formation, learning, and emotional processing. Therefore, astrocyte-neuron «crosstalk» results essential for understanding the brain as an integrated system rather than as isolated parts.

Details
Interneurons constitute a minority (15%) of cortical neurons but embody much of the neuronal genetic diversity. What evolutionary advantage might have driven this disproportionate diversity of interneurons? While the scientific community agrees that this diversity is essential for brain function, our ability to dissect their functional roles has been limited until recent years. In this symposium, we bring together four speakers from diverse disciplines, ranging from development to learning and memory, who exemplify the complexity and significance of integrating interneuronal diversity into the investigation of the neural mechanisms of behavior.

Details
Recent advances on cell-specific/single-cell profiling and modulation technologies have allowed detailed characterization of specific neural populations during physiological and pathological conditions. In neurodegenerative diseases, early altered activity of brain circuits is associated with transcriptional and pathophysiological changes affecting specific cell types and their interactions, including excitatory and inhibitory neurons. In Alzheimer’s disease (AD), excitatory neurons are the main degenerating population, although emerging evidence indicate that early dysfunction of GABAergic interneurons mediate excitatory/inhibitory (E/I) imbalance, leading to hyperexcitability and memory loss. In this symposium, we will present recent findings on the cellular and molecular mechanisms mediating E/I dysfunction of neural circuits in neurodegenerative diseases, including AD.

Details
This symposium delves into a rapidly advancing area of cognitive neuroscience that remains underexplored: Numerical cognition or «Number sense», which refers to the innate ability to perceive and estimate quantities. This fundamental cognitive skill relies on an evolutionary conserved mechanism in all vertebrates. This symposium will uniquely combine insights from genetics, neurobiology, and comparative psychology to uncover the biological underpinnings of this vital cognitive process.
