… his team expected to confirm that key proteins called NMDA receptors act specifically in neurons in layer 4 of the … Researchers used a genetic technique to knock out NMDA receptors in layer 4 of the visual cortex of mice. The cortex … mixed.  However, while the evidence demonstrates that NMDA receptors in layer 4 neurons are indeed necessary for the …

… on the presynaptic neuron must perfectly align with the receptors on the postsynaptic neuron. “All of our work is … was a change in the alignment of the synaptic chemical receptors. They also test if the synapses’ ability to … synapse. Agrin is important for organizing acetylcholine receptors in the synapse. Acetylcholine is a neurotransmitter …

… obey it. They used a chemical tag to watch how key “AMPA” receptors changed in the synapses and saw that synaptic … with reduced amount of Arc were able to express more AMPA receptors whereas increased Arc in neighboring spines caused those synapses to express less AMPA receptors. “We think Arc maintains a balance of synaptic …

… to neural activity, that helps regulate the number of receptors for the neurotransmitter glutamate at excitatory … synapses or that decreased the proper cycling of glutamate receptors within synapses. The findings show how genetic …

… ganglia circuits. These deep brain circuits, which contain receptors that mediate the effects of cannabis, are known to … effects of cannabinoids. Her team recently found that CB1 receptors are tightly linked to dopamine — a neurotransmitter … a member of the McGovern Institute, will examine how CB1 receptors in the striatum, a deep brain structure implicated …

… impulses called action potentials, can bind to specialized receptors on the root-like structures of the receiving … (the “post-synaptic” area). Dendrites are covered with receptors that are either excitatory or inhibitory, meaning … strongly. This is often accomplished by adding glutamate receptors to the dendritic spine so that the same signal is …

… might require the molecular activation of their NMDA receptors. The lab had seen that knocking out the receptors across the visual cortex prevented the increase in … layers of the cortex but that it seemed to depend on NMDA receptors on a population of excitatory neurons in layer 6, …

… if they knocked out the inhibitory cells’ endocannabinoid receptors then the place cells did a poorer job of … Fan will knock out the inhibitory cells’ endocannabinoid receptors and measure whether the place cells fail to show …
