Inhibitory Neurons Hear Themselves during Development
Miniature synaptic events, resulting from spontaneous presynaptic release of neurotransmitter in the absence of an action potential, are often used to assay neural connectivity and are thought to play a pivotal role in the development and maintenance of neuronal circuits. In this issue of Neuron, Trigo et al. identify a new class of miniature synaptic event, called "preminis," that originate fr...
متن کاملMesoprefrontal Dopamine Neurons Distinguish Themselves
By distinguishing groups of dopamine neurons that differ in their projection patterns and intrinsic properties, Lammel and colleagues report in this issue of Neuron that mesocorticolimbic dopamine neurons of the ventral tegmental area (VTA) form a distinct subclass of dopamine cells.
متن کاملDevelopment of inhibitory synapses among striatal neurons in vitro.
The development of excitatory and inhibitory synaptic connections has been studied in postnatal neurons from the caudate and putamen maintained in tissue culture. Excitatory postsynaptic potentials which were sensitive to the glutamate antagonist CNQX (6-cyano-7-nitroquinoxaline-2,3-dione) appeared between 4 and 8 d in vitro. This is the first indication that glutamatergic excitatory neurons ma...
متن کاملIntrinsic physiology of inhibitory neurons changes over auditory development.
During auditory development, changes in membrane properties promote the ability of excitatory neurons in the brain stem to code aspects of sound, including the level and timing of a stimulus. Some of these changes coincide with hearing onset, suggesting that sound-driven neural activity produces developmental plasticity of ion channel expression. While it is known that the coding properties of ...
متن کاملExperience-Dependent Bimodal Plasticity of Inhibitory Neurons in Early Development
Inhibitory neurons are heterogeneous in the mature brain. It is unclear when and how inhibitory neurons express distinct structural and functional profiles. Using in vivo time-lapse imaging of tectal neuron structure and visually evoked Ca(2+) responses in tadpoles, we found that inhibitory neurons cluster into two groups with opposite valence of plasticity after 4 hr of dark and visual stimula...
