Male and female mice have different brain cells
Study identifies rare brain cell types that are unique to male mice, and others that are unique to females. The cells were discovered in the hypothalamus, a region of the brain that governs both aggression and mating behaviors.... Read More...
Study provides possible explanation of how a seizure is able to spread through the brain
A new study implicated interneurons and pyramidal cells in the ability of a seizure to spread through the brain.... Read More...
First step to induce self-repair in the central nervous system
Severed axonal segments signal to Schwann cells to begin actin sphere formation and axon disintegration. If the process is disrupted, axon disintegration is slowed and axon fragments impair nerve regeneration.... Read More...
Discovery reveals prolific ability of Schwann cells to generate myelin
Schwann cells are much more prolific in generating myelin than previously believed. Knocking out the fbxw7 gene in mouse models, researchers discovered individual Schwann cells began to spread myelin across many axons.... Read More...
Connecting neurons in the brain
The phosphatase Prl-1 plays a key role in specifying where to form the highest density of synaptic connections on a neuron. ... Read More...
A comprehensive map of how Alzheimer’s affects the brain
Axon myelination is significantly disrupted in patients with Alzheimer's disease. Researchers also found brain cells of men and women vary significantly in how their genes respond to the neurodegenerative disease.... Read More...
New research offers insight into the proteins in the brain that detect cannabis
The secretory pathway delivery of cannabinoid type 1 receptor is axonally based, and surface expressed CB1R is more stable in axons than dendrites.... Read More...
The Key Function of Specialized Cells in Peripheral Nerve Repair
Study sheds light on how macrophages use a specific cell signalling pathway to control peripheral nerve repair following damage.... Read More...
Two Windows Into the Brain
A new study reveals a direct link between altered brain activity and social deficits in ASD.... Read More...
Discovery Opens New Opportunities to Slow or Reverse Multiple Sclerosis
Researchers report oligodendrocytes may be critical to the remyelination process.... Read More...
Astrocytes Regulate Signal Speeds of Neurons
Researchers say astrocytes play a vital role in information processing by altering neurotransmission speeds and changing the thickness of myelin.... Read More...
