To test for direct contact between photoreceptors and ganglion cells, one could also employ retrograde labeling of the optic nerve, to clearly identify projection neurons, and then examine the synaptic input(s) to these cells at an ultrastructural level.
Anterograde tracing from the InM identified projections to brain regions involved in respiratory, cardiovascular, postural and oro-facial behaviours the neighbouring hypoglossal nucleus, facial and motor trigeminal nuclei, parabrachial nuclei, rostral and caudal ventrolateral medulla and nucleus ambiguus.
140 Tracing studies have specifically identified projections to lateral hypothalamic orexin neurons from several regions of the amygdala, nucleus accumbens shell, bed nucleus of the stria terminalis, laterodorsal tegmental area, basal forebrain cholinergic neurons, GABAergic neurons in the preoptic area, and serotonergic neurons in the median/paramedian raphe nuclei.
Norris, B. J., Coleman, M. J. & Nusbaum, M. P. Pyloric motor pattern modification by a newly identified projection neuron in the crab stomatogastric nervous system.
The only identified projection to the rostromedial subdivision is from the ipsilateral posterior neocortex, which contributes RL- and RS-terminals.
The data presented are from identified projection neurons.
Perception from 2D coordinates can optionally identify perspective projections, specifically: Fischer, Haworth, and Chair projections.
Different methods permitted to identify afferent projections to RVL, from the hypothalamic paraventricular nucleus [ 3], the lateral hypothalamic area [ 4], the dorsal raphe nucleus [ 5] and from other regions [ 4].
We identify the projection from L6e to L4 as 1 of the 4 i-specific projections (Table 2) based on the EM study in the cat by McGuire et al. (1984), providing sparse and partial data.
Here we present a general technique designed to automatically identify the projection images of particles.
