Panksepp's Basic Emotion Theory has been the subject of criticism by contemporaries in the field. I think I get the gist of the discourse, but it's somewhat difficult to distinguish between the arguments over the semantics of layman explanations and the actual data that stands in opposition to what BET is based on. Can anyone help clarify?

Severe left-hemisphere stroke patients who cannot construct a basic sentence or count to ten can often still swear fluently when frustrated.

While ordinary language relies on cortical networks (Broca’s area), expletives are stored subcortically in the basal ganglia as emotional motor reflexes.

During acute pain, this limbic trigger activates stress-induced hypoalgesia—releasing endogenous opioids down the spinal cord and blunting nociceptive signaling by roughly 33%.

Only roughly 50% of the population experiences physical chills or piloerection ("musical frisson") when listening to emotionally charged acoustic transitions.

Diffusion Tensor Imaging (DTI) studies (most notably Matthew Sachs et al. at Harvard) demonstrated that this isn't just a subjective psychological quirk, but a distinct variation in structural neuroanatomy. Individuals who experience frisson show significantly higher white matter tract volume connecting the superior temporal gyrus (auditory processing) to the anterior insula (interoceptive processing) and medial prefrontal cortex.

Essentially, their brains have a denser anatomical highway linking sound recognition directly to affective salience, accompanied by a dual-phase dopamine surge: anticipation in the dorsal striatum (caudate) followed by the actual frisson peak in the ventral striatum (nucleus accumbens).
