Activity in an open field was quantified in a Plexiglas open-field box (43×43 cm2) with two sets of 16 pulse-modulated infrared photobeams (MED Associates, Georgia, Vermont). Data were analyzed based on total distance travelled and time spent in two zones: center (25% total area) and surround (75% total area). Statistics were performed using unpaired two-tailed t-test with Welch’s correction to assume unequal variances.
Pulse modulated infrared photobeams
Manufactured by Med Associates
Pulse-modulated infrared photobeams are a type of lab equipment used to detect and monitor movement or the presence of objects. The device generates infrared light beams that are modulated, or pulsed, and can be detected by a corresponding sensor. This allows the equipment to reliably track the interruption or disruption of the infrared beam, providing information about the target's presence and position.

Spontaneous locomotor activity was measured in brightly lit (500 lux) Plexiglas chambers (41 cm×41 cm) as described [25] (link), [26] (link), [27] (link). The chambers were located in sound-attenuating cubicles and equipped with two sets of 16 pulse-modulated infrared photobeams to record X–Y ambulatory movements at a 100 ms resolution (Med Associates, Lafayette, IN). Each mouse was placed at the center of the open-field chamber and recording was started upon mouse movement. Each mouse was given one, one-hour trial per week over a 5-month period beginning at 7 months of age. Mouse body weight was measured using an analytical balance (Denver Instrument, Arvada, CO) with a precision of 0.01 g. Body weight was assessed weekly over the 5 month period beginning at 7 months of age.

Spontaneous locomotor parameters and anxiety‐like behavior were assessed by introducing 14 experimental and 14 control males (age 26 weeks) to a conventional, brightly lit (500 lux), open field test apparatus consisting of a Plexiglas chamber (41 cm2) placed inside sound‐attenuating cubicles equipped with two sets of 16 pulse‐modulated infrared photobeams to record X‐Y ambulatory movements at a time resolution of 100 ms (Med Associates, Lafayette, IN). The test entailed three 60‐minutes sessions following 30 minutes of acclimation for three consecutive days during the light cycle.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
