Life and death of neurons in the aging brain

JH Morrison, PR Hof - Science, 1997 - science.org
Neurodegenerative disorders are characterized by extensive neuron death that leads to
functional decline, but the neurobiological correlates of functional decline in normal aging are …

Enhanced long-term potentiation and impaired learning in mice with mutant postsynaptic density-95 protein

…, Y He, MF Ramsay, RGM Morris, JH Morrison… - Nature, 1998 - nature.com
Specific patterns of neuronal firing induce changes in synaptic strength that may contribute
to learning and memory. If the postsynaptic NMDA (N-methyl-D-aspartate) receptors are …

Stress-induced alterations in prefrontal cortical dendritic morphology predict selective impairments in perceptual attentional set-shifting

…, AB Rocher, PR Hof, JH Morrison… - Journal of …, 2006 - Soc Neuroscience
Stressful life events have been implicated clinically in the pathogenesis of mental illness,
but the neural substrates that may account for this observation remain poorly understood. …

[PDF][PDF] The brain on stress: vulnerability and plasticity of the prefrontal cortex over the life course

BS McEwen, JH Morrison - Neuron, 2013 - cell.com
The prefrontal cortex (PFC) is involved in working memory and self-regulatory and goal-directed
behaviors and displays remarkable structural and functional plasticity over the life …

The ageing cortical synapse: hallmarks and implications for cognitive decline

JH Morrison, MG Baxter - Nature Reviews Neuroscience, 2012 - nature.com
Normal ageing is associated with impairments in cognitive function, including memory.
These impairments are linked, not to a loss of neurons in the forebrain, but to specific and …

Repeated stress induces dendritic spine loss in the rat medial prefrontal cortex

…, C Liston, PR Hof, BS McEwen, JH Morrison - Cerebral …, 2006 - academic.oup.com
The prefrontal cortex (PFC) plays an important role in higher cognitive processes, and in the
regulation of stress-induced hypothalamic–pituitary–adrenal (HPA) activity. Here we …

Transgenic mice expressing an altered murine superoxide dismutase gene provide an animal model of amyotrophic lateral sclerosis.

…, GW Huntley, PR Hof, JH Morrison… - Proceedings of the …, 1995 - National Acad Sciences
