The mushroom body is an insect brain structure required for olfactory learning. Its principal neurons, the Kenyon cells (KCs), form a large cell population. The neuronal populations from which their olfactory input derives (olfactory sensory and projection neurons) can be identified individually by genetic, anatomical, and physiological criteria. We ask whether KCs are similarly identifiable in...

The honeybee olfactory system is a well-established model for understanding functional mechanisms of learning and memory. Olfactory stimuli are first processed in the antennal lobe, and then transferred to the mushroom body and lateral horn through dual pathways termed medial and lateral antennal lobe tracts (m-ALT and l-ALT). Recent studies reported that honeybees can perform elemental learnin...

The lateral amygdaloid (LA) nucleus is the main input station of the amygdala for sensory afferents. However, it is unclear how the lateral nucleus transforms these inputs, because its intrinsic connectivity is poorly understood. Here, we took advantage of the fact that glutamatergic neurons of the lateral nucleus send a primarily unidirectional projection to the basomedial nucleus. Consequentl...

A surgical technique using local tissue skate flaps combined with cylinders made from a naturally derived biomaterial has been used effectively for nipple reconstruction. A retrospective review of patients who underwent nipple reconstruction using this technique was performed. Comorbidities and type of breast reconstruction were collected. Outcome evaluation included complications, surgical rev...

We used rat rubrospinal neurons as a model to study the soma-dendritic morphology of cord-projection neurons following spinal axonal injury. We examined lumbar-projection neurons following both upper cervical and lower thoracic axotomy to find out whether changes were dependent on the proximity of the lesion to the cell body. Axotomized neurons were marked with retrograde tracer and studied 4 a...

Cet article s’attache à la conception du cadre élaborée par Pier Paolo Pasolini et Gina Pane dans leurs œuvres respectives. Il s’agit d’abord d’observer le rôle dispositif de projection genèse leur rapport au cadrage. Entre corps-image plan-tableau, découpages découlent d’une « pensée projective » qui s’observe également en tant que mécanisme psychique. Cette dimension autoréflexive paradigme p...

The organization of the projection from the lateral geniculate body to the striate cortex in the squirrel monkey has been re-examined using the anterograde and retrograde transport of horseradish peroxidase (HRP) and wheat germ agglutinin conjugated to HRP. The results confirm earlier findings that the projections of the magnocellular and parvocellular layers of the lateral geniculate body term...
