  The Howard Hughes Medical Institute sponsored a lecture series called Making Your Mind: Molecules, Motion, and Memory. Two world renowned neuroscientist, Dr. Thomas Jessell, PhD. and Dr. Eric Kandel MD, presented four lectures. Dr. Kandel won the Nobel Prize in Medicine (Physiology) in 2000 for his work on synaptic consolidation (synaptic memory). In the first video, Dr. Kandel provides a historical review of neuroscience.. Other links to HHMI resources are provided throughout Unit 2. These videos are recommended for all students.

  Fiber tracks in the brain are axons that connect integrating centers. This is how these fiber tracks are classified: 1) The commissural tracks connect integrating centers horizontally between the two cerebral hemispheres 2) Association tracks connect integrating centers in same hemisphere which maybe either long and short. Therefroe, they connect grey matter between gyrus within same lobe (short) or between different lobes (long) 3) Projection fibers connect integrating centers along a vertical axis(e.g. the cerebrum to the brain stem). We can see these tracks using MRI Diffuse Tensor Imaging. ///

  The map of brain function was originally developed when there was a loss of brain tissue which resulted from war, industrial accidents, or disease. Upon examination of the brain after death, investigators correlated the damaged tissue to loss of function. Phineas Gage, Henry Molaison, and Clive Wearing suffered brain damage that contributed to our understanding about brain function. Today, we can exam brain function in living test subjects using technology like fMRI, PET, and CT. Learn more about this topic by follwoing the links below.

  Memory and Learning are examples of a "higher brain function" (i.e. in the same way that motor control is a type of higher brain function). How the brain learns, remembers, and retrieves memories are all "unsettled science", however. Scientists are working everyday to unlock the mysteries. We know learning and memory occurs fundamentally in the brain at the synaptic level. There are at least two types of memories: declarative (which is explicit-conscious-hippocampus dependent) and procedural (implicit-unconscious-hippocampus independent - but amygdala - caudate - cerebellum dependent). The following review articles (in conjunction with the HHMI resources) will give you a good introduction to the fundamental principles of memory and learning.
