The retina is a layer of tissue in the back of the eye that converts light into nerve impulses. The retina contains small, specialized neurons called bipolar cells that transmit … Continue Reading Researchers discover previously uncharted part of the eye.
Alzheimer’s disease is the most common form of dementia, affecting over 44 million people worldwide. Inside the brain, Alzheimer’s disease is characterized by loss of neurons, and presence of abnormal … Continue Reading Protein involved in Alzheimer’s proven to have a role in weakening synaptic plasticity.
Repeated alcohol exposure during adolescence results in long-lasting changes in the region of the brain that controls learning and memory, according to a research team at Duke Medicine that used … Continue Reading Researchers find that repeated alcohol exposure during adolescence results in lasting impairments.
Every time a person makes a memory, somewhere in their brain a tiny filament reaches out from one neuron and forms an electrochemical connection to a neighbouring neuron. A team … Continue Reading Mapping the neuroanatomy of a memory.
The human body consists of almost 100 billion neurons that contain synapses, point-to-point contacts for information transfer. Every function, feeling and action depends on the ability of synapses within neurons … Continue Reading New insights into the regulation of neuroplasticity.
People who carry a variant of a gene that is associated with longevity also have larger volumes in a front part of the brain involved in planning and decision-making, according … Continue Reading Brain region vulnerable to aging is larger in those with longevity gene variant.
Neurons, the cells of the nervous system, communicate by transmitting chemical signals to each other through junctions called synapses. This synaptic transmission is critical for the brain and the spinal … Continue Reading Optogenetics used to capture neuronal transmission in the live mammalian brain.
