in the somatic nervous system,
acetylcholine (ACh) stimulates skeletal muscle, causing contraction

action potentials
in the 8am physio lecture,
the biggest on campus
crammed with nursing majors,
and health science hankerers,
public health preachers,
OT saints and angels

amino acid NTs: glutamate (+) GABA (-) aspartate (+) glycine (-)

the prof wrote on a distant whiteboard
too many complained about being lost
she made a joke about feeding *******
to mice for her neuroscience research

amines: serotonin (-) dopamine (-/+) norepinephrine (+/-) epinephrine (+)

STEM-dominated
when i'm just looking
to drop my roots
and press that
good earth into
the spaces between
my toes and
under my nails

but the grounds are a garden
of biodiversity from clippings
gathered by migrant habit-clad
founders more than a century ago

the soil is fertile            it is temperate
there are water filters in most residences

there is enough here for me
*(+) stimulatory (-) inhibitory (+/-) stimulatory or inhibitory depending on the type of receptor to which it binds.

there are two types of summation: spatial and temporal.

in spatial summation, many presynaptic neurons fire to a singular postsynaptic neuron.
in temporal summation, a single presynaptic neuron fires sequentially to a postsynaptic neuron.
