In older mice, adult neurons in the primary visual cortex with an increased number of "silent synapses" and lacking PSD-95, showed the same structural changes only seen previously in younger animals.
Some neurons have the ability to detect and compensate for neighboring neurons, while others do not. The findings shed new light on synaptic plasticity.
A new series of studies review the roles neuroplasticity and neurogenesis play in alcohol addiction and recovery.
A newly developed light-activated protein allows researchers to study single synapses of a neuron.
Glutamate is first released near the AMPA-type glutamate receptors, then released near the NMDA-type receptors immediately after the first signal to activate the switch for synaptic plasticity.
Enzyme activity outside of specific cell types contribute to synaptic plasticity associated with addiction behaviors.
Astrocytes, not microglia, are responsible for constantly eliminating unnecessary and excessive adult synaptic connections in response to brain activity.
Financial losses evoke neuroplasticity alterations to the auditory cortex, a new study reports.
Free radicals help control cellular processes vital for neuroplasticity and neurogenesis in mice.
Findings have implications for a better understanding of how brain plasticity occurs.
Diet-induced changes to the reward system and innate differences may predispose mice to over-eating.
Researchers discover how the brain adapts in a study of children born without a corpus callosum.
