Differential vulnerability of thalamic nuclei in multiple sclerosis

Multiple Sclerosis Journal, 2022
Objectives: Investigating differential vulnerability of thalamic nuclei in multiple sclerosis (MS). Methods: In a secondary analysis of prospectively collected datasets, we pooled 136 patients with MS or clinically isolated syndrome and 71 healthy controls all scanned with conventional 3D-T1 and white-matter-nulled magnetization-prepared rapid gradient

Contributions of Thalamic Nuclei to Declarative Memory Functioning

Cortex, 2003
In spite of the acknowledged role that the thalamus plays in declarative memory, details about the precise memory processes it is involved in and which are the structures of the thalamus that contribute to these processes remain unknown. An overview is presented of human clinical and animal experimental findings showing the involvement of the thalamus,

Cortical Inhibition of Thalamic Relay Nuclei

1968
Publisher Summary This chapter presents the experimental study analyzing cortical inhibition of thalamic relay nuclei. The experiments were carried out on 30 cats, immobilized by d‑ tubocurarine. After opening the skull of one or both of the hemispheres under ether anesthesia, the dura mater was removed and potentials were recorded from different ...

Dorsal thalamic nuclei in Caiman crocodilus

Neuroscience Letters, 2014
In Caiman crocodilus, identification of nuclei that comprise the dorsal thalamus was determined by: injections of retrograde tracers into cortex/pallium; injections of retrograde tracers into the noncortical telencephalon; and injections of anterograde tracers into thalamic nuclei.

Cortical topography of thalamic intralaminar nuclei

Brain Research, 1985
The cortical projection of the thalamic intralaminar nuclei (ILN) has been studied by injecting little amounts of horseradish peroxidase (HRP) on the cerebral cortex of the rat. All of the cortical areas (except area 17) receive ipsilateral projections from at least one nucleus of the ILN.

Lesions of the anterior thalamic nuclei and intralaminar thalamic nuclei: place and visual discrimination learning in the water maze

Brain Structure and Function, 2012
Medial thalamic damage produces memory deficits in humans (e.g., Korsakoff's syndrome) and experimental animals. Both the anterior thalamic nuclei (ATN) and rostral intralaminar plus adjacent lateral thalamic nuclei (ILN/LT) have been implicated. Based on the differences in their main connections with other neural structures, we tested the prediction ...

Pyramidal influences on ventral thalamic nuclei in the cat

Brain Research, 1983
In pericruciate cortex-ablated 'pyramidal cats', discharge changes in single neurons of ventral thalamic nuclei were studied, following stimulation of ipsilateral medullary (MPT) and contralateral cervical (CPT) pyramidal tract. It was seen that cells in ventrolateral nucleus, ventroanterior nucleus and ventromedial nucleus were not significantly (2.2%)

Stimulation of the nonspecific thalamic nuclei in relation to conditioning

Experimental Neurology, 1966
Abstract Responses of ten cats to electrical stimuli through permanently implanted electrodes in nonspecific thalamic nuclei were studied. Electrical stimuli were utilized as unconditioned stimuli during Pavlovian conditioning controlled by behavioral and the EEG criteria.

Electrophysiological methods for the identification of thalamic nuclei

Zeitschrift f�r Neurologie, 1973
To increase the precision of the anatomical localization in stereotaxic neurosurgery, three techniques are now in common use to identify the thalamic nuclei: electrophysiological recording, local stimulation, reversible local blockade. A comparison is made between the results obtained by these three methods.

Differential Contributions of Thalamic Nuclei in the Generation of Antisaccades

Journal of Neurophysiology, 2010
Our knowledge of thalamus function comes largely from anatomical studies showing, for example, that the ventroanterior (VA) and ventrolateral (VL) nuclei are connected to “motor” regions, whereas the mediodorsal (MD) nucleus is connected to prefrontal “executive” regions. Interestingly, Kunimatsu and Tanaka recently showed that preparatory signals for
