Findings shed light on the mechanisms underlying brain damage in microgravity.
The delicate balance between learning new behaviors and expressing old habits is controlled by two different populations of neurons in the dorsolateral striatum.
A new mouse line makes the state of protein balance visible in the mammalian brain for the first time, allowing researchers to investigate disorders associated with protein misfolding.
Axonal swelling in the Purkinje cells of mice had no detrimental impact on firing rate or the speed at which axons transmit signals. At peak firing rate, axons with swellings were less likely to fail than those without.
Rat study reveals place cells in the hippocampus have the same patterns of activity whether they correctly, or incorrectly recall a memory. However, when the memory is incorrect, the activity begins later and is slower.
The VGLUT protein is more abundant in the dopamine neurons of female fruit flies, rodents, and humans than in males. The finding shed light on why females have greater resilience to age-related dopamine neuron loss and disorders such as Parkinson's disease.
People with schizophrenia and other neuropsychiatric disorders may have a more permissive blood-brain barrier which allows the immune system to become more actively involved in the central nervous system. The resulting inflammation may contribute to the clinical manifestation of psychosis-like symptoms.
A new map of the basal ganglia provides a blueprint of the structure of the brain region and reveals a new level of influence connected to this area.
