Reduced Dopamine Shown to Impact Activity in Brain Motor Cortex

Reduced dopamine signaling leads to abnormal activity in the motor cortex— the part of the brain chiefly responsible for controlling movement — a new study in mice illustrates. This result helps to shed light on the biological underpinnings of Parkinson’s disease, which is characterized by abnormally low dopamine levels and by motor symptoms. The study, “Reduced Dopamine Signaling Impacts Pyramidal Neuron Excitability in Mouse Motor Cortex,” was published in eNeuro. Dopamine is a neurotransmitter, or a…
