Miniature End-Plate Potentials

Actual Screen Shot

File Name: ENDPLATE.EXE
File Size: 440 Kbytes

Description: These slides are designed to visually describe the electrical potential created by the release of one or more ACh vesicles at the neural end-plate.

Rodes (B&W vision)

Actual Screen Shot

File Name: RODS.EXE
File Size: 269 Kbytes

Description: Two files. The first present an image of a rod cell with six lables that you can click-thru. The lables include the cGMP-gated Na+ channel, K+-gated channel,
Na+/K+ active transport, Rhodopsin, G-protein w/GDP and the Enzyme.
The second file is an animated version of the labled rod file above. It presents the effects of light on the rod cell. Specifically it shows how a photon of light interacts with rhodopsin, and how the G-protein w/GDP & GTP interacts with both rhodopsin and enzyme. The animation goes on to show how the cGMP-gated Na+ channel is closed thereby changing the cells resting membrane potential from -40mV to -70 mV. This hyperpolarization is interpreted into a neurologic response that is carried to the brain. This process is continued in the file called Vision Pathways & Three Cells (downloaded separately below).

Vision Pathway & the three Cells

Actual Screen Shot

File Name: VISPATH.EXE
File Size: 530 Kbytes

Description: This file is a continuation of the Rods file above. It has a graphical representation of how light and dark effect rod cells, which in turn effect bipolar cells and then ganglion cells. The images are arranged with respective graphs showing changes in membrane potential and the background firing rate of the ganglion cell.

Normal Visual Fields

Actual Screen Shot

File Name: FIELDS.EXE
File Size: 976 Kbytes

Description: This file presents the left and right visual hemifields with respect to the nasal and temporal hemiretinas. Five visual fields are represented, including 
Left and Right Binocular vision, Left and Right Monocular vision (as blocked by the nose), and Center Binocular vision. 
You can also download an additional file called Visual Field Lesions & Geniculate Bodies (below).

Visual Field Lesions & 
Geniculate Bodies

Actual Screen Shot

File Name: LESIONS.EXE
File Size: 126 Kbytes

Description: This file presents the various visual
field lesions with respect to the right and left geniculate bodies. These animations have been divided into two sections, but on one file. 
The first section presents the normal visual fields such as the Right and Left visual hemifields separately and together. Each visual hemifield is presented twice, once with respect to the temporal hemiretinas and then the nasal
hemiretinas.
The second section presents Lesions of the Visual Pathways. The entire visual field is first presented without a lesion, and then the various lesions are presented. These include a right Optic Nerve Lesion with right monocular blindness, a Midline Optic Chiasm Lesion with bilateral temporal blindness, and finally a right Optic Tract Lesion with left temporal and right nasal blindness.

The Brain-Stem

Actual Screen Shot

File Name: BRAIN.EXE
File Size: 47 Kbytes

Description: These slides are useful for a lecture/review of the brain stem anatomy; including the relationship of the cranial nerves nuclei to their respective tracts.

These slides are meant to be used in conjunction slides or pictures of neuroanatomical cross-sections of the brain stem.
