Argyll-Robertson Pupil features

Look at the math signs around the two parts of the name: A-R.
The A has no sign in front, which in math means +A (+ Accommodate).
There is a subtract sign in front of the R (- React).
Therefore, pupil can accommodate, but can't react.

Spinal cord: converting ventral/ anterior/ motor/ efferent and dorsal/ posterior/ sensory/ afferent

A limousine:
The motor of limo is ventral and anterior on the car.
The Aerial is sensory and on the dorsal and posterior of the limo.
· Note 1: 'A' is Afferent, and also, in a limo, the aerial on the top of the trunk has a capital 'A' shape.
· Note 2: An aerial is a sensory thing: picks up radio waves.
· Note 3: If picked a limo up in your hand, can only see motor on ventral, since dorsal is covered by the hood/bonnet.

Optic chiasma: what it looks like if you're a genetics star

The optic chiasma looks the same as a chiasma in meiosis, making it easy to spot on the dissected brain.

Hypothalamus: feeding vs.satiety center

"Late night snack":
LATEral is snacking [feeding] center.
Therefore, ventromedial is satiety center.

Spinal tracts: simplified geography

2 posterior: cross at the medulla.
2 lateral: ipsilateral (same side).
2 anterior: cross at the spinal level.
· See diagram.
· Note 1: Descending tracts on left of figure, ascending tracts on right.
· Note 2: For ipsilaterals: one never crosses, one crosses at the level then doubles back farther up. The ipsilateral that crosses at the level (ventral spinocerebellar) is the ipsilateral closest to the 2 anterior ones, which also cross at the level.
· Tract names in each group:
Posterior 2: lateral corticalspinal, dorsal columns. Lateral 2: dorsal spinocerebellar, ventral spinocerebellar. Anterior 2: ventral corticospinal, spinothalamic.

Spinal tracts: Gracilus vs. Cuneatus: origin from upper vs. lower limbs

Gracilus is the name of a muscle in the legs, so Fasciculus Gracilus is for the lower limbs.
By default, Fasciculus Cuneatus must be for upper limbs.

Precentral vs. postcentral gyrus: motor vs. sensory

Just an extension of the rule that anterior = ventral = efferent = motor.
The precentral gyrus is on the anterior side of the brain, so is therefore motor.
