This study is an attempt to detect the most important modifications of physiological parameters occurring during pressure immobility in rabbits and to compare them with those recorded during animal hypnosis. Like the latter, pressure immobility is characterized by the development of high voltage slow waves in the EEG, reduction in frequency and amount of rhythmic slow activity in the hippocampus (RSA) and depression of spinal polysynaptic reflexes. Systolic and diastolic blood pressures are not modified. Duration of two types of immobility is positively correlated within individuals.

This case study investigated the utility of hypnosis to precipitate a seizure in a patient with refractory epilepsy. The patient was twice administered a hypnotic induction and a suggestion to age regress to a day when he was distressed and suffered repeated seizures. The patient did not respond to the first hypnotic suggestion; however, an epileptic seizure was observed in the second hypnotic session. Videorecording and subdural electroencephalograph recording confirmed that he suffered an epileptic seizure.

Functional neuroimaging studies show that hypnosis affects attention by modulating anterior cingulate cortex activation and uncoupling conflict monitoring and cognitive control function. Considering functional changes in the activation of the occipital and temporal cortices, precuneus, and other extrastriate visual areas, which account for hypnosis-induced altered reality perception, the role of mental imagery areas appears to be central under hypnosis.

We examined changes in brain waves and blood levels of serum cortisol during yoga exercise in 7 yoga instructors and found that alpha waves increased and serum cortisol decreased. These two measures were negatively correlated (r = -.83). Comparison with a control group of nonpractitioners is desirable.

OBJECTIVE: To determine whether correlated event-related potentials (ERPs) can be detected between the brains of spatially and sensory isolated human subjects. DESIGN AND SETTING: Simultaneous digitized electroencephalograms (EEGs) were recorded from the occipital area in pairs of human subjects placed in sound attenuated rooms separated by 10 meters. One person relaxed in one of the rooms while the other received visual stimulation while in the other room. Prior to each experiment, members of the pair were randomly designated as sender and receiver.

Since the existence of the occipitofrontal fascicle (OFF) in humans has remained controversial, we utilized diffusion tensor imaging (DT-MRI)-based segmentation and tractography to investigate its trajectory in vivo in the human. We found that the OFF is distinct from the subcallosal fasciculus or Muratoff's bundle (MB) and extends from the dorsal and medial parts of the occipital lobe as well as the dorsal, medial and inferior parietal lobules to the dorsal and medial part of the prefrontal and premotor regions.

Over the past several years meditation practice has gained increasing attention as a non-pharmacological intervention to provide health related benefits, from promoting general wellness to alleviating the symptoms of a variety of medical conditions. However, the effects of meditation training on brain activity still need to be fully characterized. Sleep provides a unique approach to explore the meditation-related plastic changes in brain function.

A 44-year-old man developed a complete homonymous hemianopia 2 days after undergoing chiropractic cervical manipulation. Thromboembolism from the vertebrobasilar circulation--as the consequence of trauma to the vertebral arteries by adjacent bones, muscles, and ligaments during twisting and extension of the neck--is the probable mechanism for occipital infarction and other strokes in this and previous cases. Other neuroophthalmic manifestations reported include Horner's syndrome and sixth nerve and gaze palsies.
