Cerebellum releases bursts of tunes of electrical signals: Scientists
Q. Researchers have found that nerve cells at which part of the brain send out electrical signals in either a constant hum or in sudden bursts, on 30th September 2015?- Published on 01 Oct 15a. Cerebrum
b. Amygdala
c. Hypothalamus
d. Cerebellum
ANSWER: Cerebellum
The decision to pick out a constant hum or sudden bursts made by cells is associated with voltage across cell membranes and input from certain regions of the brain under specific conditions. This has been demonstrated by scientists M. Sengupta and V. Thirumalai from NCBS in Bengaluru. Cerebellum, a small structure at the brain’s base controls acquisition of new motor skills, balance and coordination. Permitting these functions are nerve cells referred to as Purkinje cells neatly arranged in simple layers within the cerebellum. The tune theory shows cells receive signals from varied brain parts and send out messages to deeper layer of cerebellum.
