Within the depth-psychology corpus, 'right brain' functions as a shorthand for the right cerebral hemisphere's distinctive mode of engaging reality — holistic, contextual, embodied, and resistant to the reductions of purely linguistic, analytical cognition. The term spans a spectrum of treatment: from the richly philosophical arguments of Iain McGilchrist, who insists the right hemisphere is not the seat of irrationality but of a broader, more reality-adequate attention, to the developmental-clinical investigations of Allan Schore and Daniel Siegel, who locate early attachment regulation, trauma processing, and therapeutic change in right-hemispheric systems. Julian Jaynes contributes an archaeological dimension, associating the right hemisphere with the synthetic, spatial intelligence implicated in the bicameral mind's divine voices. Van der Kolk's neuroimaging work on trauma demonstrates that flashback states lateralize to the right, giving the concept direct clinical urgency. Lenore Thomson's Jungian-neuropsychological synthesis argues that psychological type maps onto hemispheric preference in non-obvious ways. Dean Burnett, by contrast, cautions that the folk-psychological binary of 'left-brained logical / right-brained creative' is scientifically invalid, even as the underlying lateralization research it distorts retains genuine importance. The central tension in the corpus is between reductively popular uses of the concept and its rigorous neuroscientific rehabilitation — a distinction McGilchrist prosecutes with particular force.

Siegel argues that the right brain's separateness from the left hemisphere preserves a vital, pattern-oriented, holistic mode of knowing that complements the left hemisphere's linguistic and analytic processing.

The right hemisphere presents an array of possible solutions, which remain live while alternatives are explored. The left hemisphere, by contrast, takes the single solution that seems best to fit what it already knows and latches onto it.
McGilchrist characterizes the right hemisphere as maintaining open, exploratory attention toward multiple possibilities, in structural contrast to the left hemisphere's narrowing, schema-confirming tendency.

Extraverted Thinking and Extraverted Feeling activate more areas in the left brain, but Introverted Thinking and Introverted Feeling activate more areas in the right brain.
Thomson maps Jungian psychological type onto hemispheric lateralization, arguing that introverted versus extraverted versions of the same cognitive function preferentially activate opposite hemispheres.

where the circumstances are unfamiliar, indeterminate or implicit, challenge one's bias, or are not expressed in primarily lexical terms – or require interpretation in the light of context – there will be a critical role for the right hemisphere.
McGilchrist maintains that the right hemisphere is indispensable wherever reasoning must engage ambiguity, context-dependency, or implicit meaning beyond formal lexical logic.

the right hemisphere is more involved in synthetic and spatial-constructive tasks while the left hemisphere is more analytic and verbal. The right hemisphere, perhaps like the gods, sees parts as having a meaning only within a context; it looks at wholes.
Jaynes aligns the right hemisphere's holistic, synthetic cognition with the divine voice-commands of the bicameral mind, framing hemispheric lateralization in terms of pre-conscious mentality.

a hemisphere on its own cannot properly be said to do what only a person can do: 'believe', 'intend', 'decide', 'like' and so on.
McGilchrist issues a methodological caution that attributing intentions or beliefs to hemispheres is a convenient shorthand, not a claim that the hemisphere itself is an autonomous agent.
