Inhibitory synaptogenesis in mouse somatosensory cortex.
It is widely believed that inhibitory synapses are not present or present in only small numbers in the rodent cerebral cortex during the early postnatal period when the cortex is being innervated by thalamocortical fibers. Quantitative electron microscopy was carried out on the posteromedial barrel subfield of mouse somatosensory cortex from postnatal day 4 (P4) when thalamocortical innervation...
متن کاملNlgn4 knockout induces network hypo-excitability in juvenile mouse somatosensory cortex in vitro
Neuroligins (Nlgns) are postsynaptic cell adhesion molecules that form transynaptic complexes with presynaptic neurexins and regulate synapse maturation and plasticity. We studied the impact of the loss of Nlgn4 on the excitatory and inhibitory circuits in somatosensory cortical slices of juvenile mice by electrically stimulating these circuits using a multi-electrode array and recording the sy...
متن کاملMulti-task Sequence to Sequence Learning
Sequence to sequence learning has recently emerged as a new paradigm in supervised learning. To date, most of its applications focused on only one task and not much work explored this framework for multiple tasks. This paper examines three settings to multi-task sequence to sequence learning: (a) the one-to-many setting – where the encoder is shared between several tasks such as machine transla...
متن کاملSensitivity to microstimulation of somatosensory cortex distributed over multiple electrodes
Meaningful and repeatable tactile sensations can be evoked by electrically stimulating primary somatosensory cortex. Intracortical microstimulation (ICMS) may thus be a viable approach to restore the sense of touch in individuals who have lost it, for example tetraplegic patients. One of the potential limitations of this approach, however, is that high levels of current can damage the neuronal ...
متن کاملThalamocortical connections of the primary somatosensory cortex
Although each subdivision of primary somatosensory cortex (SI) receives dense input from the thalamus, but the exact location and type of information that the fibers convey have not been identified yet. In the present study, the exact source of thalamocortical fibers to areas 2 and 3b was investigated using tract-tracing techniques. Following injection of tracer into area 3b, labeled neurons ...
