Concurrent task performance enhances low-level visuomotor learning.
O'MARA, SHANE MICHAEL; ROCHE, RICHARD (Psychonomic Society, 2007)Visuomotor association learning involves learning to make a motor response to an arbitrary visual stimulus. This learning is essential for visual search and discrimination performance and is reliant upon a well-defined neural ... -
Decoding signal processing in thalamo-hippocampal circuitry: Implications for theories of memory and spatial processing
O'MARA, SHANE; O'MARA, SHANE MICHAEL (2015)A major tool in understanding how information is processed in the brain is the analysis of neuronal output at each hierarchical level through which neurophysiological signals are propagated. Since the experimental brain ... -
Differential regulation of synaptic plasticity of the hippocampal and the hypothalamic inputs to the anterior thalamus
O'MARA, SHANE MICHAEL (2009)The hippocampus projects to the anterior thalamic nuclei both directly and indirectly via the mammillary bodies, but little is known about the electrophysiological properties of these convergent pathways. Here we ... -
Everyday episodic memory in amnestic mild cognitive impairment: a preliminary investigation
LAWLOR, BRIAN; COEN, ROBERT; O'MARA, SHANE MICHAEL (2011)Background: Decline in episodic memory is one of the hallmark features of Alzheimer's disease (AD) and is also a defining feature of amnestic Mild Cognitive Impairment (MCI), which is posited as a potential prodrome of ... -
Exploring the recollective experience during autobiographical memory retrieval in amnestic Mild Cognitive Impairment.
O'MARA, SHANE MICHAEL; LAWLOR, BRIAN; COEN, ROBERT (2010)Autonoetic consciousness refers to the ability to mentally transport oneself back in subjective time to relive elements of, or all, of a past event, and is compromised in the early stages of Alzheimer?s disease (AD). Here, ... -
Hippocampal inputs mediate theta-related plasticity in anterior thalamus
O'MARA, SHANE MICHAEL (Elsevier, 2011)Hippocampally-driven oscillatory activity at theta frequency is found in the diencephalon, but an understanding of the fundamental role of theta in the hippocampo-diencephalic circuit remains elusive. An important strategy ... -
Neural processing of Spatial Information: What we know about Place cells and what they can tell us about Presence.
O'MARA, SHANE MICHAEL (MIT Press, 2006)Brain processing of spatial information is a very prolific area of research in neuroscience. Since the discovery of place cells (PCs)(O'Keefe & Dostrovsky, "The hippocampus as a spatial map," Brain Research 34, 1971) ... -
Oscillatory Entrainment of Thalamic Neurons by Theta Rhythm in Freely-Moving Rats.
REILLY, RICHARD; O'MARA, SHANE MICHAEL (2011)The anterior thalamic nuclei are assumed to support episodic memory with anterior thalamic dysfunction a core feature of diencephalic amnesia. To date, the electrophysiological characterization of this region in behaving ... -
The Subiculum: What It Does, What It Might Do, And What Neuroanatomy Has Yet To Tell Us
O'MARA, SHANE MICHAEL (Anatomical Society of Great Britain and Ireland, 2005)The subiculum is a pivotal but under-investigated structure positioned between the hippocampus proper and entorhinal and other cortices, as well as a range of subcortical structures. The subiculum has a range of ... -
Theta-Modulated Head Direction Cells in the Rat Anterior Thalamus
REILLY, RICHARD; O'MARA, SHANE MICHAEL (Society of Neuroscience, 2011)A major tool in understanding how the brain processes information is the analysis of neuronal output at each hierarchical level along the pathway of signal propagation. Theta rhythm and head directionality are the two main ...
