Norm-based face encoding by single neurons in the monkey inferotemporal cortex

Article Abstract:

A norm-based caricaturization framework developed for human psychophysics is used to show that face-responsive neurons in the macaque monkey anterior inferotemporal cortex are tuned to a basic dimension of face perception. The variation of identity information in the photo-realistic human faces reveal that the neurons are mostly tuned around the average, identity-ambiguous face, thereby indicating a link between the tuning of neurons in the inferotemporal cortex to psychological models of face identity perception.

The geometry of the double-pulsar system JO737-3039 from systematic intensity variations

Article Abstract:

Two pulsars (PSR J0737-3039A and B) were recently discovered in highly relativistic orbits around one another. A geometrical model of the system, which contains a rapidly rotating pulsar with a spin period of 22.7ms and a slow companion with a spin period of 2.77s, is presented.

Double trouble for neurons

Article Abstract:

Alzheimer's disease associated with mutations, in the presenilin protein is discussed. Mutant presenilin could create havoc on neuronal functions by triggering the activitation of certain genes.
