Synaptic mechanisms of direction selectivity in primary auditory cortex.
Frequency modulation (FM) is a prominent feature in animal vocalization and human speech. Although many neurons in the auditory cortex are known to be selective for FM direction, the synaptic mechanisms underlying this selectivity are not well understood. Previous studies of both visual and auditory neurons have suggested two general mechanisms for direction selectivity: (1) differential delays...
متن کاملSynaptic mechanisms in auditory cortex function.
Neurons in the auditory cortex (AC) respond to acoustic stimuli in diverse ways. Short latency responses code for the physical properties of stimuli, i.e., their frequency and intensity, whereas longer latency potentials may code for behavioral significance or other features. Despite a huge number of studies that, over the years, have reported on acoustic-evoked short and long-latency potential...
متن کاملDiverse synaptic mechanisms generate direction selectivity in the rabbit retina.
The synaptic conductance of the On-Off direction-selective ganglion cells was measured during visual stimulation to determine whether the direction selectivity is a property of the circuitry presynaptic to the ganglion cells or is generated by postsynaptic interaction of excitatory and inhibitory inputs. Three synaptic asymmetries were identified that contribute to the generation of direction-s...
متن کاملSynaptic mechanisms underlying interaural level difference selectivity in rat auditory cortex.
The interaural level difference (ILD) is a sound localization cue that is extensively processed in the auditory brain stem and midbrain and is also represented in the auditory cortex. Here, we asked whether neurons in the auditory cortex passively inherit their ILD tuning from subcortical sources or whether their spiking preferences were actively shaped by local inhibition. If inherited, the IL...
متن کاملMechanisms of direction selectivity in cat primary visual cortex as revealed by visual adaptation.
In contrast to neurons of the lateral geniculate nucleus (LGN), neurons in the primary visual cortex (V1) are selective for the direction of visual motion. Cortical direction selectivity could emerge from the spatiotemporal configuration of inputs from thalamic cells, from intracortical inhibitory interactions, or from a combination of thalamic and intracortical interactions. To distinguish bet...
