The stimulus was correlated with higher order principal components of the activity of projection neurons, which is consistent with a temporal encoding scheme.
These studies show that oscillations caused by synchronized activity of projection neurons (first interneurons of the insect olfactory pathway), and that GABAergic local interneurons in the antennal lobe are essential for such synchronization.
A whirl of speedy activity, with projections, music, dancing and short skits, "Haggadah," directed and choreographed by the troupe's leader, Dan Safer, is theater for the short-attention-span, when-do-we-eat?
When viewed by real-time low-light microscopy, β2-actinin peptide-treated cells were attached but exhibited dynamic membrane activity, with projections extending and retracting around the perimeter of the cell.
The SCN uses a continuously active glutamatergic projection and a rhythmically active GABAergic projection to control the activity of the sympathetic pre-autonomic neurons in the PVN.
A BFS algorithm is used to reconstruct the patient's internal structural or functional activity from collected projection data.
Moreover, we [21] could previously show that NPS, via NPSRs in the EPN, alters the activity of both projection neurons and interneurons in the BLA, leading to a disturbed expression of contextual fear memory.
Our current observations reveal that the slow-rhythmic intrinsic activity of LA projection neurons can be reinforced through neuromodulatory inputs like NPS, enhancing oscillations in the lower theta frequency band (3 6 Hz) with little effects on firing rates but providing time windows for synchronizing LA neuronal activity with afferent inputs.
One explanation is that these small responses are sufficient to elicit activity in the projection neuron post-synaptic to the Or42a sensory neuron.
Furthermore, midbrain activity, encompassing dopamine projection neurons, was accurately predicted by trial-by-trial variations in model-based estimates of precision.
We performed a sliding cross-correlation of the electrophysiological activity with the projection of the video onto the 50 PCs with the largest eigenvalues.
