Neurons in the cortical area 5 are active when a cat is straddling an obstacle.
Electrical and chemical signals are used by neurons to communicate with one another at contact points called synapses.
Long-term memory requires the activation of CREB, turning on specific genes that support new synaptic growth.
The fetal brain grows enormously during pregnancy, both in terms of its size and the number of neurons it has.
Early LTP (short-term memory) depends on a calcium-dependent protein kinase to strengthen an existing synapse.
Late LTP (long-term memory) involves dopamine activation of CREB to support new synaptic growth.
Illustrates how providing leptin to an obese mouse rapidly rewires its hypothalamus neurons.
Genes associated with autism affect the structure and function of neuronal synapses.
