Is digoxin a drug of the past? — Cleveland Clinic Journal of Medicine
digoxin MOA diagram
digoxin blocks sodium-pot atpase pump & thus prevents removal of sodium ions from cell . this low ECF sodium inturn stops sodium-calcium exchanger to remove calcium from cell.

Findings - Ethnographic Study Looks at Gossip in the Workplace - NYTimes.com
when going gets tough, when gossip gets mean, one reliable escape line: DON'T WE HAVE SOME WORK TO DO HERE?
-
If, say, an office rival seems poised to trash one of your absent allies, Dr. Hallett suggests you make a “pre-emptive positive evaluation.” A quick “Isn’t she doing a great job?” might be enough to stop the attack.
-
If your rival tries persisting with indirect sarcasm — “Oh, real great job” — you can force the issue by calmly asking what that means. That simple question, a dare made in a pleasant voice, often silenced the sarcastic gossips observed by Dr. Hallett.

AUDITORY AND VESTIBULAR PATHWAYS
-

-
Endolymph is very similar to intracellular
fluid: it is high in potassium and low in sodium. The ionic composition
is necessary for vestibular and auditory hair cells to function
optimally. The space between the membranous and bony labyrinths
is filled with perilymph, which is very much like normal
cerebral spinal fluid. - 27 more annotations...
Aequanimitas | Life in the Fast Lane
-
The title of this page, Aequanimitas, gives due reverence to the great hero of modern clinical medicine, Sir William Osler
. Osler enthusiastically encouraged his medical colleagues to embrace interests outside of the profession to protect, preserve and promote their ability to maintain their equanimity despite the daily struggles of being a doctor. -

Receptive field - Wikipedia, the free encyclopedia
-

-
There are two types of bipolar cells: "on-center" and "off-center". An on-center cell is stimulated when the center of its receptive field is exposed to light, and is inhibited when the surround is exposed to light. Off-center cells have just the opposite reaction.

Eye and Retina
-
retina, seven
layers of alternating cells and processes which convert a light
signal into a neural signal ("signal transduction").
The actual photoreceptors are the rods and cones,
but the cells that transmit to the brain are the ganglion cells.
The axons of these ganglion cells make up the optic nerve -
pupillary sphincter muscle constricts the pupil like a purse-string, and is under the control of the parasympathetic system. Therefore it is innervated by fibers from the oculomotor nerve which originate in the Edinger-Westphal nucleus of the midbrain.

Left:
Four recordings from a typical on-
center retinal ganglion cell. Each record is a
single sweep of the oscilloscope, whose
duration is 2.5 seconds. For a sweep this
slow, the rising and falling phases of the
impulse coalesce so that each spike appears
as a vertical line. To the left the stimuli are
shown. In the resting state at the top, there
is no stimulus: firing is slow and more or
less random. The lower three records show
responses to a small (optimum size) spot, a
large spot covering the receptive-field cen-
ter and surround, and a ring covering the
surround only. Right: Responses of an off-
center retinal ganglion cell to the same set
of stimuli shown at the left. - 2 more annotations...
Central Visual Pathways
-
ganglion cell axons leave the retina, they
travel through the optic nerve -
optic tract wraps around the cerebral
peduncles of the midbrain to get to the lateral geniculate
nucleus (LGN). The LGN is really a part of the thalamus,
and remember that nothing gets up to cortex without synapsing
in thalamus first (if the cortex is the boss, the thalamus is
an excellent secretary). Almost all of the optic tract axons,
therefore, synapse in the LGN. The remaining few branch off to
synapse in nuclei of the midbrain: the superior colliculi
and the pretectal area. - 8 more annotations...
Basic visual pathway
-
lateral geniculate
nucleus (LGN), where all the axons must synapse. From there,
the LGN axons fan out through the deep white matter of the brain
as the optic radiations, which will ultimately travel to
primary visual cortex -
The image projected onto your retina can be cut
down the middle, with the fovea defining the center. - 9 more annotations...
