Altered processing of corollary discharge in thalamic lesion patients
"... Accumulating evidence suggests that thalamic nuclei relay corollary discharge information of saccadic eye movements, enabling the visual system to update the representation of visual space. The present study aimed to explore the effect of thalamic lesions in humans on updating-related cortical proce ..."

Storage and executive processes in the frontal lobes.
- Science,
, 1999
"... The human frontal cortex helps mediate working memory, a system that is used for temporary storage and manipulation of information and that is involved in many higher cognitive functions. Working memory includes two components: short-term storage (on the order of seconds) and executive processes th ..."

and control tasks thus reveals activations due to the process of interest (6). These paradigms contrast with standard neuropsychological tasks that may have diagnostic value for patients with frontal cortical lesions but that do not reveal individual cognitive processes. Storage Processes and the Frontal
A neuropsychological theory of multiple systems in category learning
- PSYCHOLOGICAL REVIEW
, 1998
"... A neuropsychological theory is proposed that assumes category learning is a competition between separate verbal and implicit (i.e., procedural-learning-based) categorization systems. The theory assumes that the caudate nucleus is an important component of the implicit system and that the anterior ci ..."

cingulate and prefrontal cortices are critical to the verbal system. In addition to making predictions for normal human adults, the theory makes specific predictions for children, elderly people, and patients suffering from Parkinson's disease, Huntington's disease, major depression, amnesia
Stereotaxic display of brain lesions.
- Behav. Neurol.
, 2000
"... Traditionally lesion location has been reported using standard templates, text based descriptions or representative raw slices from the patient's CT or MRI scan. Each of these methods has drawbacks for the display of neuroanatomical data. One solution is to display MRI scans in the same stereo ..."

Feeling Sounds after a Thalamic Lesion
"... Objective: The ventrolateral nucleus of the thalamus (VL), based on its connectivity with the cerebellum and motor cortex, has long been considered to be involved with motor functions. We show that the human VL also plays a prominent role in sensory processing. Methods: Structural magnetic resonance ..."
Abstract

resonance imaging and diffusion tensor imaging were used to localize a small lesion restricted to the right VL in a patient with contralesional sensory processing deficits. Systematic assessments of anatomic brain organization and behavioral measurements of somatosensory and visual processing were conducted
Altered Error Processing following Vascular Thalamic Damage: Evidence from an Antisaccade Task
, 2011
"... Event-related potentials (ERP) research has identified a negative deflection within about 100 to 150 ms after an erroneous response – the error-related negativity (ERN)- as a correlate of awareness-independent error processing. The short latency suggests an internal error monitoring system acting ra ..."

PAPER Evidence of thalamic disinhibition in patients with
"... Objectives: Hemichorea sometimes occurs after lesions that selectively involve the caudate nucleus, putamen, and globus pallidus. Some reports have hypothesised that the loss of subthalamic nucleus control on the internal segment of the globus pallidus, followed by the disinhibition of the thalamus ..."

Primary Somatosensory Cortex Activation Is Not Altered in Patients With Ventroposterior Thalamic Lesions
"... Background and Purpose—We know remarkably little about the mechanisms underlying cortical activation. Such mechanisms might be better understood by studying the effect of well-localized lesions on the cortical activations in simple paradigms. 15 Methods—We used H2 O and positron emission tomography ..."

We compared the results with those obtained in 6 patients with thalamic lesions sparing the VP nuclei and 6

Damage to the medial region of the thalamus, both in clinical cases (e.g., patients with infarcts or the Korsakoff’s syndrome) and animal lesion models, is associated with variable amnesic deficits.
