This recorder is intended to simplify the assessment of data gathered from photoelectric actometers registering total locomotor movements. The information is presented automatically in two forms: (1) a curve of total activity over a 24 hour period, (2) a bar graph of the activity in each 30 minute time interval. A further trace is used to enable the time of onset of bursts of activity to be judged with reasonable accuracy. A particular advantage lies in the fact that the recording pens are stationary, making it possible to plot the outputs from several activity counters across the whole width of the recording paper. Standard electrical components which are easily available are used throughout the equipment.
