Architectonic subdivisions of neocortex in the tree shrew (Tupaia belangeri).

29 Jun 2009 Tree shrews are small mammals that bear some semblance to squirrels, but are actually close relatives of primates. Thus, they have been extensively studied as a model for the early stages of primate evolution. In this study, subdivisions of cortex ... Read more...

Acoustic features to arousal and identity in disturbance calls of tree shrews (Tupaia belangeri).

11 May 2009 Across mammalian species, comparable morphological and physiological constraints in the production of airborne vocalisations are suggested to lead to commonalities in the vocal conveyance of acoustic features to specific attributes of callers, such ... Read more...

A precise form of divisive suppression supports population coding in the primary visual cortex.

29 Apr 2009 The responses of neurons in the primary visual cortex (V1) to an optimally oriented grating are suppressed when a non-optimal grating is superimposed. Although cross-orientation suppression is thought to reflect mechanisms that maintain a ... Read more...
