Not exact matches

«Although running induces both substantial changes in number and morphology of young neurons as well as significant changes in learning behavior, this does not prove a causal relationship,» noted Professor Bischofberger, «Nevertheless, our results, together with previous findings, suggest that the enhanced pattern separation during memory testing is most likely mediated via running - induced increase in adult neurogenesis.»

«Rapid access to large quantities of neurons will be useful for testing a significant number of pharmacological drugs in order to identify those capable of preventing the death of motor neurons,» concludes Cécile Martinat.

While Htt null KO mice do not survive to birth (Duyao et al., 1995; Nasir et al., 1995; Zeitlin et al., 1995), mice expressing a 50 % reduction of endogenous htt levels reveal cognitive and motor deficits (Nasir et al., 1995) and significant decreases in the number of neurons in globus pallidus and subthalamic nucleus (O'Kusky et al., 1999).

(A) hGDABMP transplantation led to significant increases in numbers of NeuN + neurons counted in a 1.8 mm length of spinal cord encompassing the injury site.

Significant increases in neuron numbers were not observed in lamina 4, 5, 6 adjacent to injury centers, despite rescue of neurons more distal to the zone of injury; an outcome most likely due to neuron loss resulting from direct trauma to these laminae at time of injury.

(B) Analysis of neuron survival within laminae immediately adjacent to the site of injury shows that hGDABMP transplantation promoted significant protection of neurons when all laminae were considered (4 to 9), with the most robust increases in neuron numbers in intermediate (7) and ventral (8 and 9) gray matter laminae.

There were no significant differences in the number of doublecortin - positive neurons between genotypes, nor was there a significant interaction of genotype and exercise.

The numbers of neurons in our brains begin to decrease at the age of thirty and some neurological diseases can result from significant loss.
