Dynamical adaptation in photoreceptors.

Adaptation is at the heart of sensation and nowhere is it more salient than in early visual processing. Light adaptation in photoreceptors is doubly dynamical: it depends upon the temporal structure of the input and it affects the temporal structure of the response. We introduce a non-linear dynamical adaptation model of photoreceptors.

Repair of intraoperative aortic dissection associated with malperfusion syndrome using a combination of open and endovascular techniques.

Intraoperative aortic dissection is a rare but potentially fatal complication of cardiac surgery. In this report, we present a case of intraoperative aortic dissection that was complicated by intestinal ischaemia. The aorta was successfully repaired using both open and endovascular techniques.

[Anesthesia for thermocoagulation of the trigeminal nerve. Use of propofol].

Propofol has been used in anesthesia for trigeminal nerve thermocoagulation. 9 patients were studied. This anesthetic agent allows speedy arousal of good enough quality for patient questioning.
