Scientists have bioengineered, in neurons cultured from rats, an enhancement to a cutting edge technology that provides instant control over brain circuit activity with a flash of light.
A multidisciplinary team from Stanford University has combined neuroscience and chemical engineering to develop a process that renders a mouse brain transparent, no slicing required.
A specific pattern of neuronal firing in a brain reward circuit instantly rendered mice vulnerable to depression-like behavior induced by acute severe stress.
Researchers have isolated the neurons responsible for determining whether or not exerting effort in order to complete a task is worth the energy -- a discovery which could help medical professionals better deal with depression and other brain-related disorders.
Researchers at Stanford University School of Medicine have been able to switch on, and then switch off, social-behavior deficits in mice that resemble those seen in people with autism and schizophrenia, thanks to a technology that allows scientists to precisely manipulate nerve activity in the brain.
A new study sheds light--both literally and figuratively--on the intricate brain cell connections responsible for anxiety.
Stimulation of a distinct brain circuit that lies within a brain structure typically associated with fearfulness produces the opposite effect: Its activity, instead of triggering or increasing anxiety, counters it.
Researchers at Stanford University were able to use light to induce normal patterns of muscle contraction, in a study involving bioengineered mice whose nerve-cell surfaces are coated with special light-sensitive proteins.
Recently, brain researchers have gained a powerful new way to troubleshoot neural circuits associated with depression, Parkinson's disease and other conditions in small animals such as rats.
