Analysis of excitatory synaptic action in pyramidal cells using whole‐cell recording from rat hippocampal slices.
These experiments provide a detailed description of the dual receptor mechanism operating at hippocampal excitatory synapses and an electrophysiological method for estimating the electrotonic distance of synaptic inputs.
Modulation of synaptic transmission and long-term potentiation: effects on paired pulse facilitation and EPSC variance in the CA1 region of the hippocampus.
The sensitivity of paired pulse facilitation (PPF) and EPSC variance to changes in synaptic transmission was investigated and the results were compared with the changes in these parameters evoked by long-term potentiation (LTP).
Revised nomenclature for avian telencephalon and some related brainstem nuclei
The standard nomenclature that has been used for many telencephalic and related brainstem structures in birds is reviewed, with a rationale for each name change and evidence for any homologies implied by the new names.
An essential role for postsynaptic calmodulin and protein kinase activity in long-term potentiation
It is found that intracellular injection into CA1 pyramidal cells of the protein kinase inhibitor H-7, or of the calmodulin antagonist calmidazolium, blocks LTP, and LTP is blocked by the injection of synthetic peptides that are potentCalmodulin antagonists and inhibit CaM-KII auto- and substrate phosphorylation.
Multiple cell types distinguished by physiological, pharmacological, and anatomic properties in nucleus HVc of the adult zebra finch.
The neuronal classes within HVc of the songbird have different functional properties, which may be important for carrying specific information to their postsynaptic targets.
Excitatory synaptic currents in Purkinje cells

The results indicate that both types of excitatory input to adult Purkinje cells are mediated exclusively by glutamate receptors of the non-NMDA type, and that these cells entirely lack NMDA receptors.
A Telencephalic Nucleus Essential for Song Learning Contains Neurons with Physiological Characteristics of Both Striatum and Globus Pallidus
It is suggested that area X contains a pathway equivalent to the “direct” striatopallidothalamic pathway through the mammalian basal ganglia, with the striatal and pallidal components intermingled in one nucleus.
Striatal Dopamine Modulates Basal Ganglia Output and Regulates Social Context-Dependent Behavioral Variability through D1 Receptors
It is proposed that DA acts on D1 receptors in Area X to modulate the BG output signal and trigger changes in song variability.
Two-Stage, Input-Specific Synaptic Maturation in a Nucleus Essential for Vocal Production in the Zebra Finch
Synaptic maturation events can be temporally distinct and input-specific and may play different roles in behavioral plasticity.
Avian brains and a new understanding of vertebrate brain evolution
An international consortium of neuroscientists has reconsidered the traditional, 100-year-old terminology that is used to describe the avian cerebrum, requiring a new terminology that better reflects these functions and the homologies between avian and mammalian brains.
