Lack of early pattern stimulation prevents normal development of the alpha (Y) retinal ganglion cell population in the cat.

Binocular deprivation of pattern vision (BD) early in life permanently impairs global motion perception. With the SMI-32 antibody against neurofilament protein (NFP) as a marker of the motion-sensitive Y-cell pathway (Van der Gucht et al. [2001] Cereb.

Cytoarchitecture of the mouse neocortex revealed by the low-molecular-weight neurofilament protein subunit.

The expression patterns of the medium- and high-molecular-weight subunits of the neurofilament protein triplet have been extensively studied in several neuroanatomical studies. In the present study, we report the use of the low-molecular-weight neurofilament protein subunit (NF-L) as a reliable marker within the neurofilament protein family to reveal the regional architecture of mammalian neocortex. We document clearly its usefulness in anatomical parcellation studies and report unique expression patterns of NF-L throughout the mouse neocortex.

A claim in search of evidence: reply to Manger's thermogenesis hypothesis of cetacean brain structure.

In a recent publication in Biological Reviews, Manger (2006) made the controversial claim that the large brains of cetaceans evolved to generate heat during oceanic cooling in the Oligocene epoch and not, as is the currently accepted view, as a basis for an increase in cognitive or information-processing capabilities in response to ecological or social pressures. Manger further argued that dolphins and other cetaceans are considerably less intelligent than generally thought. In this review we challenge Manger's arguments and provide abundant evidence that modern cetacean brains are large in order to support complex cognitive abilities driven by social and ecological forces.
