The evolution of cognitive neuroscience is rooted in historical events that sparked scientific inquiry into the brain-mind relationship. Gazzaniga, Ivry, and Mangun (2018) highlight that the origins trace back to a 1650 incident involving Anne Greene, whose miraculous survival after being hanged prompted early dissections of the brain—pivotal in understanding brain functions. This event led to anatomical studies by Thomas Willis and showcasing of brain regions, providing foundational knowledge of the brain’s structure and function. The term "cognitive neuroscience" was coined by George Miller in the 20th century, marking a formal recognition of studying cognitive processes in relation to neural activity. Early questions focused on whether the mind and brain are interconnected, or if they are separate entities, with monism asserting that mental processes are entirely rooted in brain activity (Gazzaniga et al., 2019). These debates laid the groundwork for modern neuroscience and transformed perspectives on mental illnesses, such as schizophrenia, which was once misunderstood as purely behavioral, but now recognized as involving complex neural mechanisms (Insel, 2010). Such scientific advances demonstrate how understanding brain structures and functions offers insights into human behavior, cognition, and mental health.

A guiding principle in ethics within neuroscience research is respect for persons, which emphasizes informed consent and autonomy. This is particularly crucial when working with human participants, ensuring they comprehend the scope, risks, and benefits of a study (American Psychological Association, 2017). When research involves animals, principles like beneficence and justice guide humane treatment, minimizing suffering and ensuring fair distribution of research benefits (National Institutes of Health, 2016). These principles safeguard the rights of subjects, foster trust, and uphold scientific integrity. A probing question for further discussion is: How can researchers balance the ethical considerations between advancing scientific knowledge and safeguarding the welfare of vulnerable populations in neuroscience research?

The lesion method remains a fundamental approach to studying neural functions by observing behavioral changes following localized brain damage. If a person exhibits impaired language abilities after a stroke, this indicates the affected brain region’s role in speech. EEG measures electrical activity across the brain non-invasively, capturing waveforms associated with different states such as sleep (delta waves) or wakefulness (alpha waves). fMRI, on the other hand, detects brain activity by measuring blood flow changes linked to neural activation, providing spatial information about active regions during cognitive tasks (Rogers et al., 2020). Psychophysiological methods, including heart rate and galvanic skin responses, monitor physical and mental states, revealing how biological signals correlate with psychological processes. These methods collectively deepen our understanding of how neural systems support cognition, emotion, and behavior, highlighting the importance of multimodal approaches in neuroscience research.

Electroencephalography (EEG) records electrical activity from the scalp, offering real-time monitoring of brain states. Its non-invasive nature makes it ideal for studying consciousness, sleep, and cognitive processes. For example, different EEG waveforms—delta, alpha, beta—are associated with specific mental states (Gazzaniga et al., 2018). Event-related potentials (ERPs) extend EEG by isolating neural responses to specific stimuli, aiding in the diagnosis of disorders such as multiple sclerosis where delayed neural responses can be detected. Magnetoencephalography (MEG) measures magnetic fields generated by neural activity, providing high temporal and spatial resolution but requiring expensive equipment and magnetic shielding. These neuroimaging techniques allow researchers to map brain activity patterns linked to behavior and cognition, enhancing our understanding of neural dynamics underlying various mental health conditions.
