(Medical Xpress)—The fruit fly Drosophila melanogaster is a model organism (a non-human species that is extensively studied to understand particular biological phenomena) studied in a wide range of laboratory experiments ...
Losing the activity of a key ion channel in the brain may contribute to the buildup of a devastating and toxic protein responsible for the clumps of plaque that accumulate in Alzheimer's disease, a team of neurobiologists ...
Our brains are made of billions of neurons, which are connected forming complex networks. They communicate between themselves by sending electrical signals, known as action potentials, and chemical signals, known as neurotransmitters, ...

(Medical Xpress)—An enduring neurobiological mystery is why do vertebrate rods and cones shut down their transmitter release in response to a light stimulus. If that particular question is too broad, then consider a slight ...
A new genome-wide association study (GWAS) estimates the number of different places in the human genome that are involved in schizophrenia.

(Medical Xpress)—Sensory adaptation is a familiar phenomenon. Whether jumping into a cold pool, or driving through manure-laden air as you pass by a recently fertilized farm, an initially strong sensory experience generally ...
(Medical Xpress)—At the same settings and light conditions, a camera will take the same picture every time. In contrast, a brain does not make perfect reconstructions of a stimulus. It appears instead to accumulate evidence ...
