Individual differences in locomotor activity and sensitization
Pharmacology Biochemistry and Behavior, 1991Male rats were screened for locomotor activity in a novel environment and divided into high (HR) and low (LR) responders based on whether their locomotor activity score for the first hour was above or below the median locomotor activity for the subject sample.

Octopamine and locomotor activity of rats
Psychopharmacology, 1983Intracerebroventricular administration of P-octopamine (OA) had opposite effects on locomotor activity depending on whether or not the rats were subjected to uncontrollable electric shocks. In unshocked rats, OA produced a large decrease in locomotor activity, but when the rats were subjected to unsignalled and uncontrollable electric shocks, a ...

Masking of locomotor activity in hamsters
Journal of Comparative Physiology A: Sensory, Neural, and Behavioral Physiology, 1999The inhibition of locomotion by light (masking) was investigated in Syrian hamsters. When 1-h pulses of light were presented in the early night, activity was strongly suppressed by irradiances of about 1 lx or greater. Ultradian light-dark cycles were used as another way to study masking.

Locomotor activity in the ischemic gerbil
Brain Research, 1993Previous studies have shown that within 24 h after ischemic insult, gerbils exhibit an increase in locomotor activity. Because activity gradually diminishes to normal levels with repeated testing, it has been argued that this behavior represents a reversible or transient effect of ischemia.

Locomotor activity: a complex behavioural trait to unravel
Behavioural Processes, 2003 Locomotor activity in Drosophila, as in other organisms, is an important trait since it is at the basis of almost all behaviours. Indeed, the locomotor centre is implicated in all complex behaviours consisting of a change in the position of the animal ...

Locomotor activity in spinal man
Gait & Posture, 1994We studied whether spinal locomotor centres of patients with paraplegia can be activated by external stimuli. In patients with complete paraplegia, coordinated stepping movements were induced by weight support and standing on a moving treadmill. The pattern of leg muscle electromyographic (EMG) activity was similar to that seen in healthy subjects ...

Locomotor activity and anorexogenic action
Psychopharmacologia, 1969A method is described with which it is possible to measure locomotor activity and food intake simultaneously in the same rat or other small animal. From a study of a number of psychomotorstimulant drugs and anorectic agents it may be concluded that locomotorstimulation and appetite-suppression are two different effects that may or may not characterize ...

A Recorder of Locomotor Activity
The American Journal of Psychology, 1967The apparatus described here was designed to register only locomotor behavior and also to minimize sensory feedback from S's activity. It is inexpensive, simple to construct, and easy to service. The activity cage, shown in Fig. 1, consists of a circular alley with a lamp at its center and four photocells spaced equally around its outer wall.

Altered locomotor activity in neuropsychiatric patients
Progress in Neuro-Psychopharmacology and Biological Psychiatry, 1986Movement was monitored continuously for 24-48 hours in representative neuropsychiatric patients, using a wrist-worn portable piezoelectric activity monitor with solid-state memory. Striking differences were observed in both circadian and more rapid (ultradian) rhythms between these patients and normal controls of a similar age.

Estradiol concentration and the regulation of locomotor activity
Physiology & Behavior, 1995We predicted that female prairie voles (Microtus ochrogaster) would not increase in locomotor activity during "induced" proestrus. We developed and tested two alternative a priori hypotheses to explain this predicted lack of activity. The Non-Response Hypothesis in which voles cannot, physiologically, increase activity in response to estradiol and, the
