ENDOVASCULAR ULTRASOUND. Photo essay from La Louvière clinic, France (59). Endovascular ultrasound is a technic of imagery that permits to study in real time (in vivo) the inner wall and the light of the vessels. The device is constituted by a generator of ultrasounds, that send a signal of a determined frequency to a transductor of small diameter, placed inside a catheter. The return signal is caracterised by an acoustic impedance, proportional to the density of the tissue and to the vel

SYNAPSE. SYNAPSE LTP (long-term potentiation). Mechanism of LTP (long-term potentiation), which plays a role in learning. Stage 1 (See images no. 11969 05 and 11970 05 for stages 2 and 3). In response to a stimulus (sight, taste, touch, etc.), an electrical signal is produced which triggers the release of massive quantities of glutamate (purple triangles) by the presynaptic element. This in turn triggers a massive release of calcium (red spheres) in the dendrite (postsynaptic element), se
