JoVE Behavior
JoVE Behavior documents observational and experimental techniques that seek to understand human and animal behavior. Work in this field includes analysis of genetic causes and physiological responses to internal or external stimuli as well as the implicated brain regions.

Transcranial Magnetic Stimulation for Investigating Causal Brain-behavioral Relationships and their Time Course

1Cognitive, Perceptual & Brain Sciences, University College London


JoVE 51735

Transcranial magnetic stimulation (TMS) is a technique for non-invasively disrupting neural information processing and measuring its effect on behavior. When TMS interferes with a task, it indicates that the stimulated brain region is necessary for normal task performance, allowing one to systematically relate brain regions to cognitive functions.

Early Metamorphic Insertion Technology for Insect Flight Behavior Monitoring

1Department of Electrical and Computer Engineering, North Carolina State University


JoVE 50901

We present a novel surgical procedure to implant electrodes in Manduca sexta during its early metamorphic stages. This technique allows mechanically stable and electrically reliable coupling with the neuromuscular tissue to study flight neurophysiology dynamics. We also present a novel magnetic levitation platform for tethered studies of insect yaw.

Behavioral Assessment of the Aging Mouse Vestibular System

1Discipline of Biomedical Science, University of Sydney, 2The Bosch Institute Animal Behavioural Facility, University of Sydney


JoVE 51605

Motor control and balance performance are known to deteriorate with age. This paper presents a number of standard noninvasive behavioral tests with the addition of a simple rotary stimulus to challenge the vestibular system and show changes in balance performance in a murine model of aging.

Compensatory Limb Use and Behavioral Assessment of Motor Skill Learning Following Sensorimotor Cortex Injury in a Mouse Model of Ischemic Stroke

1Psychology Department, Illinois Wesleyan University, 2Division of Medical Sciences, University of Victoria


JoVE 51602

Mouse models have become increasingly popular in studies of behavioral neuroscience. As models advance, it is important to develop sensitive behavioral measures specific to the mouse. This protocol describes the Pasta Matrix Reaching Task, which is a skilled motor task for use in mouse models of stroke.

Inchworming: A Novel Motor Stereotypy in the BTBR T+ Itpr3tf/J Mouse Model of Autism

1Departments of Paediatrics and Clinical Neurosciences, Alberta Children's Hospital Research Institute, University of Calgary Faculty of Medicine, 2Department of Psychology, Neuroscience Program, Trinity College


JoVE 50791

Inchworming is a highly repetitive synchronous digging motion displayed by BTBR T+ Itpr3tf/J (BTBR) mice when placed in a testing cage with sufficient sawdust bedding. The procedure is a modification of the juvenile social interaction protocol and is used here to assess repetitive motor stereotypies relevant to Autism Spectrum Disorder.

Cortical Source Analysis of High-Density EEG Recordings in Children

1Cognitive Neuroscience & Neuropsychiatry Section, UCL Institute of Child Health, 2Academic Division of Neonatology, Institute for Women's Health, University College London


JoVE 51705

In recent years, there has been increasing interest in estimating the cortical sources of scalp measured electrical activity for cognitive neuroscience experiments. This article describes how high density EEG is acquired and how recordings are processed for cortical source estimation in children from the age of 2 years at the London Baby Lab.

Flat-floored Air-lifted Platform: A New Method for Combining Behavior with Microscopy or Electrophysiology on Awake Freely Moving Rodents

1Neuroscience Center, University of Helsinki, 2Neurotar LTD, 3A. I. Virtanen Institute for Molecular Sciences, University of Eastern Finland, 4Laboratory Animal Center, University of Helsinki


JoVE 51869

This method creates a tangible, familiar environment for the mouse to navigate and explore during microscopic imaging or single-cell electrophysiological recordings, which require firm fixation of the animal’s head.

Fat Preference: A Novel Model of Eating Behavior in Rats

1Center for Addiction Research, Department of Pharmacology and Toxicology, University of Texas Medical Branch


JoVE 51575

Dietary fat content influences both energy intake and body fat composition in mammals. By examining rats’ preference for high fat food in a series of choice experiments, it is possible to test genetic differences and pharmacological interventions on their preference for high fat food.

Eye Tracking, Cortisol, and a Sleep vs. Wake Consolidation Delay: Combining Methods to Uncover an Interactive Effect of Sleep and Cortisol on Memory

1Department of Psychology, Boston College, 2Department of Psychology, Wofford College, 3Department of Psychology, University of Notre Dame


JoVE 51500

We present a protocol used to discover an interactive effect between sleep and cortisol on memory consolidation, particularly for negative arousing images. Specifically, the experimental design utilizes eye tracking, salivary cortisol analysis, and behavioral memory testing – methods that can be used with both healthy and clinical participants.

Stimulating the Lip Motor Cortex with Transcranial Magnetic Stimulation

1Department of Experimental Psychology, University of Oxford


JoVE 51665

Transcranial magnetic stimulation (TMS) has proven to be a useful tool in investigating the role of the articulatory motor cortex in speech perception.  This article describes how to record motor evoked potentials (MEPs) from the lip muscles and how to disrupt the motor lip representation using repetitive TMS.
