An ischemic stroke is a type of stroke that occurs when a blood clot in an artery, also known as thrombus, or the progressive narrowing of arteries, blocks the blood and oxygen flowing to the brain. This process can cause both temporary and permanent brain damage, for instance, leading to partial paralysis, cognitive impairments and other debilitating impairments.

Statistics suggest that older age increases the risk of experiencing ischemic strokes. While neuroscience studies have shed light on many of the physiological processes underpinning strokes, the immune responses following these events and promoting recovery remain poorly understood.

Researchers at the Institut Blood and Brain @ Caen-Normandie (BB@C), University of Edinburgh and other institutes in Europe carried out a study exploring how central nervous system (CNS)-associated macrophages (CAMs), immune cells residing at the CNS interfaces, contribute to post-stroke immune responses.

It’s an unprecedented look into prehistoric anatomy.

The roadmap to promote neural repair after spinal cord injury remains elusive. Here, longitudinal single-cell sequencing in adult zebrafish identifies intersecting modes of neuronal plasticity and neurogenesis during innate neural repair.

Personal identity seems so strong. We have the same sense of ourselves throughout our lives, even though everything about our physical bodies and brains is changing constantly. What then causes the continuity of personal identity? Where does transhumanism fit in? Some say personal identity is an illusion, but that seems like cheating. Others credit a nonphysical soul. That seems as though it’s cheating too.

The hippocampus geometrically represents both physical location and abstract variables on a neural manifold in mice performing a decision-making task in virtual reality.

Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue than traditional two-photon microscopy, the new approach could provide a clearer view of how neurons communicate in real time, leading to new insights into brain function and neurological diseases.

A better understanding of emergent phenomena like the wetness of water, where the properties of a system can’t be explained by those of its constituent parts, could unravel some big mysteries.

This study shows that by enhancing internal complexity of neurons in a Hodgkin–Huxley network, similar performance to larger, simpler networks can be achieved, suggesting an alternative path for powerful AI systems by focusing on neuron complexity.

Cornell University research demonstrates that sleep resets the hippocampus, enabling continuous learning and offering new strategies for treating memory-related disorders.

While everyone knows that a good night’s sleep restores energy, a new Cornell University study finds it resets another vital function: memory.

Learning or experiencing new things activates neurons in the hippocampus, a region of the brain vital for memory. Later, while we sleep, those same neurons repeat the same pattern of activity, which is how the brain consolidates those memories that are then stored in a large area called the cortex. But how is it that we can keep learning new things for a lifetime without using up all of our neurons?
