[Pharmaceutical preparations in the hospital. Analysis and in-house development of an automated system of management.].

Introduction: In the past couple of years, the demand of galenic compounds has risen sharply. In order to plan the activity, our team designed and set up a database which stores all the necessary information related to drugs and ingredients. This allows our internal Galenic Laboratory to better manage the pharmaceutical prescriptions for the hospital and the outpatients, optimizing the use of raw materials.

Complexity and competition in appetitive and aversive neural circuits.

Decision-making often involves using sensory cues to predict possible rewarding or punishing reinforcement outcomes before selecting a course of action. Recent work has revealed complexity in how the brain learns to predict rewards and punishments. Analysis of neural signaling during and after learning in the amygdala and orbitofrontal cortex, two brain areas that process appetitive and aversive stimuli, reveals a dynamic relationship between appetitive and aversive circuits.

The STN beta-band profile in Parkinson's disease is stationary and shows prolonged attenuation after deep brain stimulation.

Producing accurate movements may rely on the functional independence of sensorimotor circuits within basal ganglia nuclei. In parkinsonism there is abnormal synchrony of electrical activity within these circuits that results in a loss of independence across motor channels. Local field potential (LFP) recordings reflect the summation of local electrical fields and an increase in LFP power reflects increased synchrony in local neuronal networks.

Cone signal interactions in direction-selective neurons in the middle temporal visual area (MT).

Many experimental measurements support the hypothesis that the middle temporal visual area (MT) of the rhesus monkey has a central role in processing visual motion. Most of these studies were performed using luminance stimuli, leaving open the question of how color information is used during motion processing. We investigated the specific question of how S-cone signals, an important source of color information, interact with L,M-cone signals, the dominant source of luminance information.

Effect of head position on postural orientation and equilibrium.

This study examined (1) how changes in head position affect postural orientation variables during stance and (2) whether changes in head position affect the rapid postural response to linear translation of the support surface in the horizontal plane. Cats were trained to stand quietly on a moveable platform and to maintain five different head positions: center, left, right, up, and down. For each head position, stance was perturbed by translating the support surface linearly in 16 different directions in the horizontal plane.
