An Introduction to Behavioral Neuroscience
0 Views •
2023
Behavioral neuroscience is the study of how the nervous system guides behavior, and how the various functional areas and networks within the brain correlate to specific behaviors and disease states. Researchers in this field utilize a wide variety of experimental methods ranging from complex animal training techniques to sophisticated imaging experiments in human subjects. This video first offers a historical overview of some of the major milestones that lead to our current understanding of the...

Source: Hamna J. Qureshi and Craig J. Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana Here we will highlight the key similarities and differences of noninvasive blood pressure measurement techniques between humans and rodents and examine the engineering principles that govern blood pressure. The principles that govern current cuff technology to acquire systolic and diastolic pressures will also be discussed. Commercially available cuffs that connect...

2026
The cognitive neuroscience approach to development focuses on how the central nervous system supports emerging cognitive abilities. Neuroimaging and behavioral studies link specific neural systems to memory and cognitive processing in infancy.Distinct Memory Systems in the Developing BrainInfant long-term memory includes two distinct systems: implicit and explicit memory. Implicit, or nondeclarative, memory involves unconscious recall of skills and routines. It develops early and appears in...
FAQs
EEG detects electrical voltage changes at the scalp, giving investigators a noninvasive readout of neural activity. This signal allows studies of brain processes related to cognition, perception, and behavior without surgical entry. Its role is primarily measurement: it captures electrical changes for analysis rather than using pulses to alter activity.
Functional magnetic resonance imaging tracks blood-oxygen-level changes associated with neural activity. These changes provide a way to investigate brain function while participants remain available for repeated measurements. In neuroscience, the method is useful when the research question concerns how brain activity relates to cognition, perception, behavior, or neurological disorders.
Transcranial magnetic stimulation uses magnetic pulses to induce currents in targeted cortical regions. This makes it distinct from approaches that primarily detect signals, because it is used to modulate neural activity. Researchers can therefore apply it when the goal includes influencing a selected cortical area as part of work on brain function or brain-based interventions.
The choice depends on whether the study needs electrical voltage changes, blood-oxygen-level changes associated with activity, or induced currents in a targeted cortical region. EEG and functional magnetic resonance imaging provide measurements, whereas transcranial magnetic stimulation is used to influence activity. Matching the method to the research question helps align the measured or induced effect with the intended investigation.
These approaches let neuroscientists examine how brain processes relate to cognition, perception, and behavior, as well as investigate neurological disorders. Because they can be used with living participants without surgical entry, they support research designs involving repeated measurements. Their value lies in connecting neural activity with observable mental or behavioral phenomena.
Beyond basic research, noninvasive neuroscience contributes to clinical assessment, rehabilitation, and the development of brain-based interventions. The methods provide ways to study neural processes in relation to neurological disorders and to pursue applications addressing clinical needs. This connection extends neuroscience from describing brain function toward assessing and developing potential interventions.
