Cultured cells in microfluidic chambers enable systematic experiments at the synapse.
The early stages of Alzheimer's disease are thought to occur at the synapse, since synapse loss is associated with memory dysfunction.
UCLA cellular neuroscientists are providing new insights into the mechanisms that underlie long-term memory â€” research with the potential to treat long-term memory disorders.
Neurons experience large-scale changes across their dendrites during learning, say neuroscientists at The University of Texas at Austin in a new study that highlights the important role that these cell regions may play in the processes of learning and memory.
