Which Object Appeared Longer?

In this issue of Neuron, Genovesio et al. report that neurons in the frontal cortex encode the relative duration of appearance of two sensory signals, together with the features of each signal. Such representations could provide a neural basis for episodic memory.

Object features, object locations, and object files: which does selective attention activate and when?

The representation within which attention operates was investigated in 3 experiments. The task was similar to that of R. Egly, J. Driver, and R. D. Rafal (1994). Participants had to detect the presence of a target at 1 of 4 ends of 2 shapes, differing in color and form. A precue appeared at 1 of the 4 possible corners. The 2 shapes occupied either the same or different locations in the cuing an...

The powerful illusion of a unified, Cartesian self responsible for intentional action is contrasted with the biologically sounder model of competitive processes that yield an only partially coherent agency, and the existence of the illusion of self is explained as an evolved feature of communicating agents, capable of responding to requests and queries about their own decisions and actions.

A case of proliferative diabetic retinopathy in which scintillating particles appeared in the intravitreal cavity after laser photocoagulation

BACKGROUND To report a case of proliferative diabetic retinopathy (PDR) exhibiting the appearance of scintillating particles presumed to be crystallin inside the intravitreal cavity after laser photocoagulation. CASE PRESENTATION A 56-year-old male patient presented at our outpatient clinic after becoming aware of decreased vision in his right eye. Ocular examination performed at the patient'...
