Moved from a psychology degree to a PhD in neuroscience - an electrophysiological investigation of the sources of sensory input to dopamine releasing neurons. From there I moved back to psychology with an experimental postdoc looking at perception with sensory substitution devices. I am looking to move back into neuroscience with my next postdoc, but in the meantime I'm blogging on a mixture of psychology and neuroscience.

Trigeminal anatomy (in which my basic Adobe Illustrator skills improve)

I’ve been having a bit more of a practice with Adobe Illustrator (CS2), and with the help of these few posts from Prof Like Substance and a more extensive guide on the MIT website, and I can now do the basics without wearing out Ctrl, Z, and my patience. So here’s the fruits of the last hour or so’s efforts (click to embiggen):

The outlines of the trigeminal nerve ganglion and brainstem trigeminal nuclei in a rat (transverse section).

A diagram of the afferent and efferent connections of the brainstem trigeminal nuclei.

1: Lemniscal pathway

2: Paraemniscal pathway

3: Extralemniscal pathway

Abbreviations: 5G: trigeminal nerve ganglion; Pr5: principal trigeminal nucleus; Sp5o: spinal trigeminal nucleus oralis; Sp5ir: spinal trigeminal nucleus interpolaris, rostral subdivision; Sp5ic: spinal trigeminal nucleus, caudal subdivision; Sp5c: spinal trigeminal nucleus caudalis; SC: superior colliculus; Pom: medial part of the posterior thalamic nuclei group; VPM: ventral posterior medial thalamic nucleus; VPMvl: venterolateral region of the ventral posterior medial thalamic nucleus.
