Rapid voluntary limb movements are accompanied by a triphasic electromyogram (EMG): the agonist muscle discharges briefly to generate the initial limb displacement and then, in sequence, an antagonist and second agonist burst occur. The origins of these bursts of EMG have been attributed to both peripheral and central sources. We attempted to determine in… (More)
1. The relation of somatosensory cortex (SI) neuronal activity to actively maintained limb posture was examined by recording from single neurons in the SI of monkeys trained to hold the forearm at different pronation-supination postures and to exert different directions and magnitudes of steady torque. 2. Neurons related to limb position were, in most cases… (More)
BACKGROUND Optimal cellular immunotherapy for cancer should ideally harness both the innate and adaptive arms of the immune response. Lymphokine-activated killer cells (LAKs) can trigger early innate killing of tumour targets, whereas long-term adaptive-specific tumour control requires priming of CD8+ cytotoxic lymphocytes (CTLs) following acquisition of… (More)
