Human neurons have fewer ion channels compared to other animals. The reduced number of ion channels may have allowed the human brain to divert energy to other neural processes, researchers say.
Electrophysiology
Electrophysiology research articles can cover research involving whole cell patch-clamp recordings, voltage clamping, current clamping, multielectrode arrays, EEG, brain machine interfaces, field potentials, neural prosthetics, deep brain stimulation, synaptic plasticity and other work.
Nicotine exposure significantly altered the metabolism and secretion of serotonin, acetylcholine, kynurenic acid, and choline in HT22 hippocampal cells. Findings suggest nicotine could have neuroprotective properties and provide cognitive enhancement.
A new study reveals the mechanisms by which neurons and astrocytes work together to form synapses.
Dopamine-controlled fan cells in the lateral entorhinal cortex are required for the formation of associative memories.
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.
FPP, an intermediate in the mevalonate pathway, may trigger cell death in certain situations. The findings shed new light on neurological damage caused by stroke.
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.
