KAUST researchers collaborated with the Blue Brain Project to study astrocytes, brain cells crucial for memory and learning. Dr. Corrado Calì produced 3D models of astrocytes using serial block-face electron microscopy to understand their structure. The study, published in Progress in Neurobiology, reveals how lactate transfer from astrocytes to neurons contributes to brain energy usage. Why it matters: Understanding astrocyte function could lead to new drugs for treating conditions like stroke and Alzheimer's disease by improving brain cell function.
KAUST and EPFL Blue Brain Project researchers propose a new theory about a 'secret language' used by cells for internal communication regarding the external world. Using a computational model, they suggest that metabolic pathways can code details about neuromodulators that stimulate energy consumption. The model focuses on astrocytes and their cooperation with neurons in fueling the brain. Why it matters: This suggests a new avenue for understanding information processing in the brain and how cells contribute to the energy efficiency of brains compared to computers.
MBZUAI researchers are developing spiking neural networks (SNNs) to emulate the energy efficiency of the human brain. Traditional deep learning models like those powering ChatGPT consume significant energy, with a single query using 3.96 watts. SNNs aim to mimic biological neurons more closely to reduce energy consumption, as the human brain uses only a fraction of the energy compared to these models. Why it matters: This research could lead to more sustainable and energy-efficient AI technologies, addressing a major challenge in deploying large-scale AI systems.
KAUST held its first Enrichment in the Spring (SEP) program from March 20–28, focusing on the human brain and mind, coinciding with Brain Awareness Week. The program featured lectures from neuroscientists like Professor Alim-Louis Benabid, and presentations by KAUST's Ali Awami and Corrado Cali on visualization technology for studying the brain. KAUST researchers are collaborating with the Human Brain Project and Harvard University to develop comprehensive brain models and visualize connectome data. Why it matters: This initiative highlights KAUST's commitment to advancing neuroscience research and fostering interdisciplinary collaborations to understand the complexities of the human brain.
KAUST researcher Corrado Calì won an award at the Brainstorming Research Assembly for Young Neuroscientists (BraYn) in Italy for his work on glycogen modulation and synapse stabilization. Calì presented research in collaboration with KAUST Professor Andrea Falqui and Dr. Elena Vezzoli from the University of Milan, investigating the lactate shuttle's involvement in synaptic plasticity. Calì and KAUST colleagues are also collaborating with the Blue Brain Project to produce a computer simulation of astrocyte-neuron coupling, using 3D virtual reality to investigate brain cell morphologies at the nanoscale. Why it matters: This award recognizes KAUST's contribution to neuroscience research and highlights the university's collaborative efforts in understanding brain plasticity and developing advanced tools for studying brain structures.
KAUST's Vice President of Research, Professor Pierre Magistretti, presented the 2023 Nansen Neuroscience Lecture in Oslo. The lecture highlighted his discovery of the astrocyte-neuron lactate shuttle and its role in brain physiology and pathology. His research explains how astrocytes feed neurons lactate as a primary energy source, impacting memory and cognition. Why it matters: The lecture recognizes KAUST's contribution to neuroscience and highlights the importance of understanding brain energy consumption for treating neurological disorders.
KAUST Discovery highlights the contributions of Magistretti to the field of neuroenergetics. His research explores the cellular and molecular basis of brain energy metabolism and brain imaging. Magistretti's group discovered mechanisms underlying the coupling between neuronal activity and energy consumption, revealing the role of astrocytes. Why it matters: Understanding brain energy metabolism and the role of glial cells can advance brain imaging techniques and our understanding of neuronal processes.
KAUST Professor Pierre Magistretti received the 2016 Fondation IPSEN Neuronal Plasticity prize for his work in neuroenergetics. The award recognizes Magistretti's contributions to understanding the relationship between neuronal activity and brain energy consumption. He shares the award with Dr. David Attwell and Dr. Marcus Raichle, and will be honored at FENS in Copenhagen. Why it matters: This award highlights KAUST's contribution to international neuroscience research and strengthens its reputation in biological and environmental science.
