Searching the web, search engines and lessons.
The Cyberlibrarian" offers simple lessons on how to effectively search the internet.  Lesson 5 may be particularly helpful with instructions on how to find links to images on the web such as Image Finder from UC Berkely.

Looksmart.com is a search engine that can be useful for finding biographical information on people such as Alan L. Hodgkin or Andrew F. Huxley

Using About.com you can narrow down your search to find neuroscience related links which include:  a review of the cranial nerves, neuroscience-related dictionaries and education resources related to neurotransmitters, olfaction, vision, taste, vestibular system, somatosensory systems, and more.

Raging Search from AltaVista.com is a text-only search engine which gives fast results.

Neuroguide.com is a searchable and browsable index of neuroscience resources including neurobiology, neurology, neurosurgery, psychiatry, psychology, cognitive science sites and information on human neurological diseases.

Search PubMed for articles published in scientific journals using keywords.

A few on-line atlases:

The Digital Anatomist is a neuroanatomy interactive syllabus containing 3-D computer graphic reconstructions of brain material; MRI scans; tissue sections, some enhanced with pathways; gross brain specimens and dissections; and summary drawings.

An interactive brain atlas from Washington University may be useful for the student.

The Whole Brain Atlas from Harvard University compliles information from several different neuroimaging techniques.

The Medical Education Information Center (MediC) has a searchable website where you can find information and illustrations on the spinal cord and meninges, or on the histology of the skin including sensory receptors.

The organization of the Vertebrate Retinal by Helga Kolb, Eduardo Fernandez and Ralph Nelson. Everything you could want to know about the retina can be found on this site, including anatomy and physiology, retinal circuits, neuroactive substances, glutamate receptors and color vision. The site has links to illustrations and movies.  Especially interesting is the page of facts and figures concerning the human retina

Here, the 6 readily identifiable layers of the cerebral cortex are explored.

From the University of Toronto, Canada, illustrations of the structure of the basilar membrane along with detailed text explain how the membrane responds to sound waves.

Some specific links which may help with internet assignments:

Cochlear Fluids Composition

Electrolyte Composition of Various Body Fluids

The Na+-K+-ATPase (Sodium Pump)

Channel gating, including S4 movement

Neurons

Sodium Pump a and ß-subunit Assembly

Biographical links:

The Nobel Prize is the first international award given yearly since 1901 for achievements in physics, chemistry, medicine, literature and peace.
Search the Nobel e-museum for biographies of laureates such as Alan L. Hodgkin and Andrew F. Huxley (1963 for medicine) or Walther Hermann Nernst (1920 for chemistry)

This link provides additonal biographical information on Hodgkin and Huxley.

In two reports in the journal Science, a research team led by investigator Roderick MacKinnon at The Rockefeller University unveils the crystal structure that shows the potassium channel's surprising architecture. This link provides more information on MacKinnon.

Movies:

a 584 mpeg movie showing the motor system with cortex

3D movies of the monkey brain

At this link you will be prompted to download a 2.85 mb Quicktime movie illustrating parts of the brain in 3D. The download takes about 12 minutes on a 33.6 kbs connection and requires a quicktime player to view.

These movies show the retinal ganglion cell growth cones as they navigate throught the living retinal neuroepithelium.

Additonal movies made by Judy Drazba at NIH show cultured growth cones from chick retinal ganglion cells growing on various purified substrates.

Animations:

Interactive Flash animations from the University of Utah Medical School such as this one on the oculocephalic reflex and another animation showing voluntary control of facial muscles and effects of a tumor in the cortex, an infection of the mastoid process, or a vascular occlusion in the pons are instructive. Their gallery of scientific illustrations and animations might be of additional interest.
