Three groups of rats were trained to perform a differential discrimination task in a 2-tone operant conditioning paradigm. One group received electrolytic lesions of the medial septal nuclei, another received electrolytic or knife cut lesions of the entorhinal cortex. These groups were compared with a normal control group. Recordings of granule cells in the fascia dentata were obtained in all a...

We studied the effects of lesions in the ventrolateral medulla, in a region coinciding with the cell bodies of the Al group of catecholamine neurons. After bilateral electrolytic lesions at three contiguous rostrocaudal levels (obex and at 1 and 2 mm caudal to the obex), mean arterial pressure increased by 40 mm Hg in the conscious rabbit. This rise in pressure was associated with increased res...

In mixed wastewater streams, the presence of metal ions can retard the destruction of organic contaminants and the efficiency of recovery of the metal is reduced by the presence of organic species. The reduction in the efficiency of these methods is due to the formation of complexes between the organic species and the metal ions in solution. Results are presented for copper-2,4,5-T system in wh...

During the aluminum electrolysis process is produced at cathode and CO2 gas bubbles are generated on anode released. The reduce active surface area of anode, which increases energy consumption. They also cause liquid to fluctuate oxidize again. study anodic bubble behavior important power consumption improve current efficiency. In this paper, phase field, laminar flow tertiary distribution modu...

introduction: the dorsal striatum plays an important role in the control of motor activity and learning processes within the basal ganglia circuitry. furthermore, recent works have suggested functional differentiation between subregions of the dorsal striatum methods: the present study examined the effects of bilateral electrolytic lesions of the dorsomedial striatum on motor behavior and learn...

F sharpened tungsten needles are essential tools required for the manipulation of small particles (1, 2, 3). They can be purchased commercially from Fine Science Tools at a cost of roughly $100 for a set of ten needles. Tungsten needles can easily become damaged during routine use, and accidentally bumping the sharpened end of a tungsten needle immediately renders it useless. For laboratories t...
