A new study contradicts other research which indicates neurodevelopment weeds out most of the connections between retinal ganglion axons and target cells in the brain.
Neuroimaging study reveals decreased levels of the SV2A protein in synapses in patients with schizophrenia. The decrease in the protein could underlie the cognitive difficulties experienced by those with schizophrenia and provide new targets for treatment.
Findings shed new light on how the brain wires during development.
Working with mice, Johns Hopkins researchers say they have figured out how stem cells found in a part of the brain responsible for learning, memory and mood regulation decide to remain dormant or create new brain cells. Apparently, the stem cells “listen in” on the chemical communication among nearby neurons to get an idea about what is stressing the system and when they need to act.
Researchers discover neurons regulate their own excitability so that the activity level in networks remains as constant as possible.
A new study claims researchers have been able to reactivate memories which could not otherwise be retrieved by using optogenetics.
Researchers report ApoE4 can reduce the number of functional synapses by interfering with the DNA responsible for synapse formation and maintenance.
Researchers have pinpointed the precise cellular connections responsible for triggering overeating.
When manipulated in two lines of transgenic mice, neuroligin 1, a gene linked to ASD, produced mature adults with irreversible defects which affected either learning or social interaction. The findings could have implications for potential gene therapies for autism.
Researchers have discovered a neural pathway in which the brain controls a specific molecule, connected to bipolar disorder and schizophrenia which is also critical to the formation of long term memory.
