their discovery many descriptions of these plexuses have been published but were unable to decipher the neural pathways and circuits hidden within this distributed network of ganglia. The axons and dendrites of the enteric neurons run between ganglia and from these to the muscle layers and to other intestinal

of the input from the thalamus targets layer 4 of primary sensory cortex. Cells in that layer have the unique ability to follow patterns of afferent of input. For example, the temporal structure of neural responses in visual cortical layer 4 mirrors the firing patterns of thalamic relay cells Reponses

-tropic receptors; feedback modulation; layer 6 In the early visual pathway, information travels from the lateral geniculate nucleus (LGN) to the primary visual cortex. At this level, the relay of visual information is regulated by a network of synaptic connections, including modulatory projections from

This thesis presents CraneTracker, a multi-modal sensing and communication system for monitoring migratory species at the continental level. By exploiting the robust and extensive cellular infrastructure across the continent, traditional mobile wireless sensor networks can be extended to enable

Can the blind see? Blindsight is residual visual capacity in a field defect secondary to damaged striate cortex without conscious awareness. This phenomenon was discovered when patients with this form of field loss were given forced-choice testing. Although the subjects denied seeing anything

of connectivity described in these feed-back models is reflected Integrate-and-Fire (I&F) neurons. We have developed a reconfigurable multi-chip neuronal system for modeling feature selectivity in the local recurrent connections of our VLSI network of and applied it to oriented visual stimuli. Our system

, and then later remembered. This distinction maps directly onto the modern distinction between short-term memory (henceforth working memory) and long-term memory The emphasis on memory systems and memory processes has been quite valuable in shaping cognitive and neural models of memory. In general, this approach
