Synaptic Transmission: Excitatory Autapses Find a Function?
نویسنده
چکیده
An autapse is a synapse between a neuron and itself, a peculiar structure with an unclear function. A new study suggests that excitatory autapses contribute to a positive-feedback loop that maintains persistent electrical activity in neurons.

Distinctive quantal properties of neurotransmission at excitatory and inhibitory autapses revealed using variance-mean analysis.
Normal brain function depends on an interplay between glutamatergic and GABAergic synaptic transmission, yet questions remain about the biophysical differences between these two classes of synapse. By taking advantage of a simple culture system, we present here a detailed comparison of excitatory and inhibitory neurotransmission under identical conditions using the variance-mean (V-M) method of...
متن کامل“Self” versus “Non-Self” Connectivity Dictates Properties of Synaptic Transmission and Plasticity
Autapses are connections between a neuron and itself. These connections are morphologically similar to "normal" synapses between two different neurons, and thus were long thought to have similar properties of synaptic transmission. However, this has not been directly tested. Here, using a micro-island culture assay in which we can define the number of interconnected cells, we directly compared ...
متن کاملMechanism underlying unaltered cortical inhibitory synaptic transmission in contrast with enhanced excitatory transmission in CaV2.1 knockin migraine mice
Familial hemiplegic migraine type 1 (FHM1), a monogenic subtype of migraine with aura, is caused by gain-of-function mutations in CaV2.1 (P/Q-type) calcium channels. In FHM1 knockin mice, excitatory neurotransmission at cortical pyramidal cell synapses is enhanced, but inhibitory neurotransmission at connected pairs of fast-spiking (FS) interneurons and pyramidal cells is unaltered, despite bei...
متن کاملSynaptic Transmission: Functional Autapses in the Cortex
Autapses--synapses made by a neuron onto itself--have often been observed anatomically in vivo, but their purpose has remained uncertain. A recent paper describes functional autapses in the cerebral cortex and gives clues to their physiological role.
متن کاملP24: The Role of Ionotropic Glutamate Receptors in the Induction of LTP
Long-term potentiation (LTP) is a reflection of synaptic plasticity that has an important role in learning and memory. LTP is a long-lasting increase of synaptic activity due to enhancement of excitatory synaptic transmission after a high-frequency train of electrical stimulation. The role of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors in excitatory synaptic tran...
