Models of neurodegeneration in the hippocampus : molecular and behavioural factors promoting neuroprotection and neuropathology
(Trinity College (Dublin, Ireland). School of Psychology, 2003)We investigated the consequences of brain insult after ischemia and kainic acid using different behavioural tasks, because both ischemia or KA model induce a similar neurodegenerative process to that resulting from traumatic ... -
Molecular and cellular mechanisms underlying signal transduction in the Hippocampal formation : the role of brain-derived neurotrophic factor
(Trinity College (Dublin, Ireland). School of Psychology, 2002)We investigated the possibility that BDNF might play a role in the modulation of synaptic function in the hippocampal formation. Our experiments have focused on the regulation of endogenous BDNF systems in spatial learning ... -
