Psychogenic seizures

RP Lesser - Neurology, 1996 - AAN Enterprises
A subgroup of the patients seen for the treatment of seizures are patients who do not have
epilepsy. These may constitute some 20% of patients at epilepsy referral centex 2 A ss~ ming~…

Optimizing parameters for terminating cortical afterdischarges with pulse stimulation

GK Motamedi, RP Lesser, DL Miglioretti… - …, 2002 - Wiley Online Library
Purpose: We previously reported that brief pulses of electrical stimulation (BPSs) can terminate
afterdischarges (ADs) during cortical stimulation. We investigated conditions under which …

Functional mapping of human sensorimotor cortex with electrocorticographic spectral analysis. II. Event-related synchronization in the gamma band.

…, DL Miglioretti, B Gordon, RP Lesser - Brain: a journal of …, 1998 - academic.oup.com
It has been shown in animals that neuronal activity in the 'gamma band' (>30 Hz) is associated
with cortical activation and may play a role in multi-regional and multi-modal integration of …

Functional mapping of human sensorimotor cortex with electrocorticographic spectral analysis. I. Alpha and beta event-related desynchronization.

…, MT Wilson, S Uematsu, RP Lesser - Brain: a journal of …, 1998 - academic.oup.com
Human scalp EEG studies have shown that event-related desynchronization (ERD) in the
alpha (8-13 Hz) and beta (15-25 Hz) bands may be used to detect functional activation of …

Placebo‐controlled pilot study of centromedian thalamic stimulation in treatment of intractable seizures

…, R McPherson, RP Lesser, B Gordon, P Schwerdt… - …, 1992 - Wiley Online Library
Stimulation of centromedian (CM) thalamic nuclei has been proposed as a treatment for
seizures. We implanted programmable subcutaneous (sc) stimulators into CM bilaterally in 7 …

…, RP Lesser, B Gordon, S Uematsu, J Hart, P Schwerdt… - Brain, 1993 - academic.oup.com
Little is known about what pathways subserve mirth and its expression laughter. We present
three patients with gelastic seizures and laughter elicited by electrical stimulation of the …

Determination of current density distributions generated by electrical stimulation of the human cerebral cortex

SS Nathan, SR Sinha, B Gordon, RP Lesser… - Electroencephalography …, 1993 - Elsevier
With the use of a 3-dimensional finite element model of the human brain based on structural
data from MRI scans, we simulated patterns of current flow in the cerebral hemisphere with …

Analysis of the clinical problems in parkinsonism and the complications of long‐term levodopa therapy

RP Lesser, S Fahn, SR Snider, LJ Cote, WP Isgreen… - Neurology, 1979 - AAN Enterprises
We evaluated the current status of 131 patients with idiopathic parkinsonism who were
