Firing properties of two types of nucleus raphe dorsalia neurons during the sleep-walking cycle and their responses to sensory stimuli
Spontaneous activity of the nucleus raphe dorsalis (NRD) neurons during the sleep-waking cycle and effects of sensory stimuli upon NRD neurons were studied in cats. Seventy-one neurons recorded… Expand
Arthritis induced in cat by sodium urate: a possible animal model for tonic pain
Abstract An attempt has been made to determine whether cats rendered arthritic by the injection of monosodium urate (MSU) crystals (rod‐shaped 40–130 &mgr;m length) into one knee joint capsule can be… Expand
Evaluation of the analgesic effects of capsaicin using a new rat model for tonic pain
An animal model for tonic pain has been produced by means of injecting monosodium urate crystals into a knee joint of rat hind paws in order to evaluate the analgesic effects of various drugs and… Expand
Stochastic properties of spontaneous unit discharges in somatosensory cortex and mesencephalic reticular formation during sleep-waking states.
1. We compared renewal and Markovian characteristics of neuronal discharge sequences in deeper layers (V and VI) of the somatosensory area I (SI) and the mesencephalic reticular formation (MRF) of… Expand

Spontaneous activities of the mesencephalic reticular formation (MRF) neurons of head-restrained cats were recorded to investigate their dynamic properties during sleep and waking. The… Expand

The mesencephalic reticular formation (MRF) neurons are regarded as contributing to the activation of the cerebral cortex. We have investigated the statistical characteristics of the single neuronal… Expand
Intracellular recordings from the lateral geniculate neurons of cats.
(1) Intracellular recordings were made in 41 neurons in the lateral geniculate nucleus (LGN) of cats anesthetized with Nembutal.(2) The LGN neurons showed either the EPSP's fluctuating in two or… Expand
Antinociceptive action of morphine and pentazocine on unit activity in the nucleus centralis lateralis, nucleus ventralis lateralis and nearby structures of the cat
Abstract Single neuronal activity has been recorded extracellularly from the nucleus centralis lateralis (CL), ventralis lateralis (VL) and medialis dorsalis (MD) of the cat thalamus. The majority of… Expand
Peripheral somatic activation of neurons in the cat red nucleus.
Excitation and inhibition in ventrobasal thalamic neurons before and after cutaneous input deprivation.
Publisher Summary This chapter describes excitation and inhibition in ventrobasal thalamic neurons, before and after cutaneous input deprivation. The neural mechanisms of the spontaneous background… Expand
