The brainstem nucleus locus coeruleus (LC) projects to nearly the entire brain, and has the capacity
to dramatically affect neural processing via release of the neurochemical noradrenaline (NE).

Surface area and gyrification measures in the human brain : a magnetic resonance imaging study
(Trinity College (Dublin, Ireland). School of Psychology, 2009)
This thesis was motivated by a clinical interest in identifying measurable brain structure markers that can be used as indicators of malformations of cortical development (MCD) in epilepsy. MCDs may manifest as abnormalities ...
High-resolution imaging of the human amygdala : role of basolateral and centromedial complexes in reward processing and associative learning .
(Trinity College (Dublin, Ireland). School of Psychology, 2012)
The amygdala is an inherently heterogeneous aggregation of nuclei. Although
the animal literature has revealed some segregation of function within these nuclei, it
has not been possible to investigate the role of human ...
An investigation into the role of impulsivity in addiction

Impulsivity typically refers to actions made without sufficient forethought or
consideration of their consequences. This dissertation focuses on the neural
underpinnings of this trait from a perspective of a striatal-based ...
The behavioural neurophysiology of stress : effects on hippocampal formation mechanisms of spatial representation
(Trinity College (Dublin, Ireland). School of Psychology, 2011)
In the fast-paced world we live in we encounter stressful situations on a continuous basis. Some stressors may cause chronic stress whereas others act only on a relatively short time basis and are regarded as acute stressors. ...

This thesis presents a discourse analytic study of Irish newspaper talk about those
described as refugees, asylum seekers and immigrants. The analysis looks at newspaper
talk from two leading Irish newspapers. The Irish ...
Neuropsychological and electrophysiological correlates of self- and error-awareness in focal lesion patients and young adults
(Trinity College (Dublin, Ireland). School of Psychology, 2009)
This thesis examines numerous aspects of deficit awareness, both among nonneurological
participants and patients with circumscribed neural injury, in
order to increase our understanding of the neuropsychological,
neuroanatomical ...
The multisensory perception of social cues in virtual crowds
(Trinity College (Dublin, Ireland). School of Psychology, 2010)
The current thesis contributes to the field of social and affective psychology,
with a focus on the perception of social cues from groups or crowds of people. While to
date there is a wealth of literature in this area on ...
