The axon initial segment (AIS) is where nerve signals begin, and its adaptability is key to brain function. Scientists have found that the AIS changes in response to activity levels, helping neurons ...
Brain cells called glia play various supporting roles to keep the system running smoothly. Between the axon of a transmitting neuron and the dendrite of a receiving neuron is a gap called the ...
The axons of a neuron – the arm-like structures that stretch out and exchange signals with other brain cells like wires – are often depicted as sausage-like cylindrical tubes, but new imaging ...
Interneurons are located exclusively in the brain and spinal cord. 1 Neurons are composed of a cell body containing the nucleus, dendrites that receive chemical, electrical, or other signals via ...
Axons and dendrites vary in size ... gaining the ability to control brain cells with the flash of a light. The cells can be programmed to react to light through genetic altering.
Michael Barresi’s research interests are focused on how glial cells help wire the nervous system in the embryonic zebrafish brain. His lab discovered that astroglial cells provide a substrate for ...
