We analyze the parameter ranges under which the voltage in a dendritic cable model exhibits bistability. We find (1) the magnitude of NMDA and GABA conductances limit the maximum cable diameter for which the system is bistable. For the investigated p

The nucleus accumbens (NAcb) integrates information from a wide range of glutamatergic afferent inputs, including the prefrontal cortex, hippocampus and amygdala. One of the glutamatergic receptors, the NMDA channel, has been implicated in the non-li

Psychophysical studies of contour detection (Kovacs et al., IOVS 37: S670 (1996); Nafziger et al., IOVS 39: S859 (1998) indicate that the effective range of surround interactions scale inversely with stimulus density. We present a model based on psyc

We investigate the effects of cellular-level cholinergic neuromodulation on the physiological properties of a realistic, anatomically reconstructed CA3 pyramidal cell model. The model has 385-compartments, contains a wide variety of ion channels (Na,

One advantage of cortical synchronization as a binding mechanism is its ability to account for phenomena such as perceptual grouping. Such a mechanism requires the ability to synchronize groups of cells and to desynchronize these groups from each oth

Recently, we proposed a cortical-based model that accounts for a range of psychophysical results on contour salience [S.C. Yen, L.H. Finkel, Vision Res. 38 (1998) 719}741]. In this model, cortical units are interconnected by long-range horizontal con

The hippocampus is known to be a critical structure for memory function, but how its anatomical, physiological, and cellular elements endow it with this function remains a mystery. As such, even less is known about how neuropathological changes assoc
