The Palacio de Congresos de Las Palmas de Gran Canaria is one of the most unique buildings in the capital of Gran Canaria. Designed by Óscar Tusquets, it was built between 1993 and 1997 with the idea of creating lighthouse to protect Las Canteras beach.

The symphony hall is the result of a perfectly harmonized design between the building’s marine setting and the capacity to accommodate 1,656 people. With dimensions of 1,650 m² , its hexagonal shape allows for extraordinary acoustics. A large window of more than 100 m² , through which the Atlantic Ocean can be seen, makes it the most spectacular piece for holding concerts.

The Palacio de Congresos de Canarias is located within the Alfredo Kraus Auditorium complex, which has the coveted ISO 9001:2000 quality certificate awarded by the Spanish Association for Standardisation and Certification (AENOR) and which guarantees the excellence of the services it offers.

It is located in the heart of Las Palmas de Gran Canaria, the most cosmopolitan city with the greatest economic and cultural dynamism in the Canary Islands. Its location, on the beachfront of Las Canteras, provides it with a unique urban and marine atmosphere with suggestive panoramic views of the Atlantic Ocean.

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.

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.

Major advances have occurred in the understanding of the cellular and molecular determinants of brain energy metabolism highlighting a novel framework of well-regulated and dynamic metabolic dialogues between different cell types. These comprise neuron-astrocyte coupling in the grey matter, and oligodendrocyte-axonal metabolic coupling in the white matter, the mechanisms of which are only beginning to be deciphered. The current conceptual understanding proposes that neuron-astrocyte and axon-oligodendrocyte partnerships function as distinct metabolic units, collaborating intricately to sustain brain function and promote the overall well-being of the organism.

Details

Astrocyte control of brain physiology is one of the hot topics in neuroscience. Although historically considered passive cells, accumulating evidence has revealed that astrocytes actively participate in regulating brain activity and behavior. They do this through metabolic processes but also by releasing neuroactive substances, termed gliotransmitters, that interact with neurons to regulate their activity. In this symposium we will review the most recent findings regarding how astrocytes regulate neuronal activity and synaptic plasticity in different brain circuits to impact animal behavior. The selected speakers are recognized experts in the field, each offering insights into different neuronal networks and expertise ranging from synaptic physiology to behavior.

Albert Compte. Leader of the Theoretical Neurobiology of Cortical Circuits Group. Fundació Clínic per la Recerca Biomèdica – Institut d’Investigacions Biomèdiques August Pi i Sunyer (FCRB-IDIBAPS), Spain.

Details

This symposium will explore the expanding role of neural cell-surface antibodies in neurological diseases. These antibodies, targeting ion channels, receptors, and synaptic proteins, are linked to a broad range of neurological symptoms. Notably, N-methyl-D-aspartate receptor (NMDAR) antibodies are commonly found in patients with psychiatric symptoms, memory deficits, and other neurological alterations. Advances in neuroimmunology have helped elucidate antibody-mediated encephalitis mechanisms using cellular and animal models. Imaging and electrophysiological studies have detailed how autoantibodies interact with cell-surface proteins, disrupting their function. Meanwhile, passive transfer models have demonstrated the pathogenicity of these antibodies in vivo, and emerging active immunization models provide deeper insights into disease immunobiology and potential therapies.

Beyond direct receptor or synaptic protein effects, neural cell-surface antibodies can also trigger innate immune responses, including microglial activation, which may contribute to antigen loss and neuronal dysfunction. However, the mechanisms driving the diversity of clinical phenotypes remain poorly understood, emphasizing the need for systematic profiling of patients’ antibodies. Additionally, these autoantibodies serve as powerful tools for studying cognitive processes, with recent findings indicating their impact on neuronal circuits involved in working memory. This symposium will present a comprehensive review of antibody-mediated mechanisms in immune-mediated neurological disorders, offering valuable insights into both disease pathogenesis and potential therapeutic advancements.

S11 Neural Mechanisms for Internal State-Dependent Animal Behavior

Details

Animal behavior is not deterministic, that is, the same sensory input will not always lead to the same behavioral output. Instead, the behavioral response exhibited by an animal is strongly influenced by its internal state, which is determined by complex body-brain interactions that include metabolic and hormonal communication as well as past experiences. A clear example of this is found in food-seeking behavior. An animal doesn’t always eat a discovered food source. Instead, its decision depends on various contextual and internal signals, such as its metabolic state, energy cost, and potential threats from predators. Consequently, the animal may prioritize safety or rest over eating if it isn’t hungry, too tired, or frightened. Understanding the complexity of how the brain integrates sensory evidence with the internal state to shape behavior is central to this symposium, which aims to showcase cutting-edge research revealing a wide array of neural mechanisms that support these flexible decisions.
