PURPOSE This study evaluated the relation of head and eye movements during ictal ipsilateral and contralateral head turning in patients with focal epilepsies with regard to lateralization of the epileptogenic zone. METHODS We reviewed our database and identified patients with ictal head turning ipsilateral and contralateral to the seizure onset as defined by ictal EEG. Twenty-seven seizures o...

Purpose. To investigate the alternation in cerebral and ocular blood flow velocity (BFV) in patients of carotid stenosis (CS) with or without contralateral carotid occlusion (CO) early after carotid endarterectomy (CEA). Patients and Methods. Nineteen patients underwent CEA for ≥50% CS. Fourteen patients had the unilateral CS, and five patients had the ipsilateral CS and the contralateral CO. T...

Skilled motor training results in reorganization of contralateral motor cortex movement representations. The ipsilateral motor cortex is believed to play a role in skilled motor control, but little is known about how training influences reorganization of ipsilateral motor representations of the trained limb. To determine whether training results in reorganization of ipsilateral motor cortex map...

Binaural interaction plays an important role in shaping response properties of central auditory neurons. Using single unit recording and iontophoresis, we examined frequency tuning curves (FTCs), interaural intensity difference (IID) curves, and rate-intensity functions of inferior collicular (IC) neurons of the big brown bat, Eptesicus fuscus, under closed system or free field stimulation cond...

Purpose: Although occult central lymph node (LN) metastases in papillary thyroid carcinoma (PTC) are common, the efficacy of prophylactic central lymph node dissection (CLND) remains controversial. This study aimed to investigate the incidence and the risk factors for occult ipsilateral central LN metastasis in patients with unilateral PTC and a clinically negative neck (cN0). Methods: We revie...

INTRODUCTION Many surgeons are using the ipsilateral rotation of the TRAM flap because of easier flap insetting and improved aesthetic outcomes; however studies evaluating these techniques are limited to case series without groups for comparison. Our purpose was to evaluate the safety of the ipsilateral technique through a retrospective cohort study. METHODS We retrospectively evaluated conse...

What promotes motor recovery from stroke? To date, studies of recovery from stroke have shown alterations in function in various cortical areas, including the contralesional (unaffected) motor cortex (M1). However, whether these changes contribute to recovery or are mere epiphenomena remains unclear. We therefore sought evidence that the ipsilateral M1 can compensate for dysfunction of the cont...

Dense reciprocal connections link the rat anterior thalamic nuclei with the prelimbic, anterior cingulate and retrosplenial cortices, as well as with the subiculum and postsubiculum. The present study compared the ipsilateral thalamic-cortical connections with the corresponding crossed, contralateral connections between these same sets of regions. All efferents from the anteromedial thalamic nu...

[Purpose] Previous studies have reported on motor deficits in the ipsilateral upper limbs (UL) of a damaged brain hemisphere in motor tasks. However, little is known about sensory deficits on the ipsilateral side. Therefore, we investigated whether both motor and sensory function of the ipsilateral UL are affected in patients with stroke. [Subjects and Methods] Fifty patients with unilateral st...

We have shown previously that ipsilateral pyramidal tract (PT) neurons facilitate the actions of reticulospinal neurons on feline motoneurons (Edgley et al., 2004), which indicates that they might assist the recovery of motor functions after injuries of contralateral corticospinal neurons. Nevertheless, stimulation of ipsilateral PT fibers alone only rarely evoked any synaptic actions in motone...
