Synaptic AMPA Receptor Exchange Maintains Bidirectional Plasticity
Activity-dependent synaptic delivery of GluR1-, GluR2L-, and GluR4-containing AMPA receptors (-Rs) and removal of GluR2-containing AMPA-Rs mediate synaptic potentiation and depression, respectively. The obvious puzzle is how synapses maintain the capacity for bidirectional plasticity if different AMPA-Rs are utilized for potentiation and depression. Here, we show that synaptic AMPA-R exchange i...
متن کاملBidirectional activity-dependent plasticity at corticostriatal synapses.
Corticostriatal projections originate from the entire cerebral cortex and provide the major source of glutamatergic inputs to the basal ganglia. Despite the importance of corticostriatal connections in sensorimotor learning and cognitive functions, plasticity forms at these synapses remain strongly debated. Using a corticostriatal slice preserving the connections between the somatosensory corte...
متن کاملBidirectional synaptic plasticity: from theory to reality.
Theories of receptive field plasticity and information storage make specific assumptions for how synapses are modified. I give a personal account of how testing the validity of these assumptions eventually led to a detailed understanding of long-term depression and metaplasticity in hippocampal area CA1 and the visual cortex. The knowledge of these molecular mechanisms now promises to reveal wh...
متن کاملBidirectional synaptic plasticity can explain bidirectional retrograde effects of emotion on memory.
Emotional events can either impair or enhance memory for immediately preceding items. The GANE model explains this bidirectional effect as a glutamate "priority" signal that modulates noradrenaline release depending on arousal state. We argue for an alternative explanation: that priority itself evokes phasic noradrenaline release. Thus, contrasting E-1 memory effects are explained by a mechanis...
متن کاملPericyte Migration
OBJECTIVE The mechanism underlying pericyte loss during incipient diabetic retinopathy remains controversial. Hyperglycemia induces angiopoietin-2 (Ang-2) transcription, which modulates capillary pericyte coverage. In this study, we assessed loss of pericyte subgroups and the contribution of Ang-2 to pericyte migration. RESEARCH DESIGN AND METHODS Numbers of total pericytes and their subgroup...
