Numerous asymmetric and symmetric chemical synapses, corresponding to the excitatory and inhibitory synapses, respectively, were seen in the neuropile
Low-voltage electrical stimulation of the oral ganglion on the lower lip of the larval mouth or the apical neuropile
between the preoral and anterolateral arms on the preoral hood region of the D.
The apical ganglion continues to grow as larvae approach competency, with the addition of immunoreactive neurons and an associated increase in complexity in the neuropile
and ciliary nerves surrounding the area.
In most decapods with stalked eyes, the optic neuropiles
are located within the eyestalks in optic lobes that form the most anterior parts of the brain.
Within the ganglion, these afferent projections and processes of intrinsic FMRFa-ir neurons form a dense FMRFa-ir neuropile
These modifications strikingly correlate with the acquisition rate and with the duration of retention, indicating that information during learning is in part processed within optic neuropiles
(Tomsic et al., 2003).
