Perhaps, sure, why not.
Assuming that sharks are as sensitive as your question indicates, and the hammer-head gives them spatial differentiation:
There's a study from 2016, it seems to be a student-project, more tentative try-it and see rather than with standardised and careful methodology. If you're prepared to just run with it, then you're sure to have a basis for convincing writing.:
The methodology is simply to show slides/video with EEG leads attached to a cohort and to correlate the results.
angry emotional reactions are very clear on the right side of the
brain involving this type of theta waves
When [...] sad [is] recorded, there are several effects or
reactions to the right side of the back of the brain. There was two
waves Delta and Theta reaction. The reaction at the Delta waves
was insignificant when compared to the waves of Theta [to sad
emotions]. However, Delta still shows the answers where the
waves are often associated with men who have a sense of
empathy and intuition. Theta waves at sad emotions relate to
[...] old memory.
Joy produced alpha-waves in the mid-brain
Delta and theta occur in shock and high stress situations (perhaps respectively, it's not stated. I'm fairly convinced that subjects might react differently to stress than to shock - It's not clearly differentiated here).
To be clear the frequency ranges related to these Greek letters and the normal state thereof is:
Delta (δ)0.5 – 3 Hz - Sleep, if awake, sense of intuition/empathy.
Theta (θ)3 – 8 Hz - Deep meditation, healing "twilight consciousness".
Alpha (α)8 – 12 Hz - Relaxed creativity, visualisation.
Beta (β)12 – 27 Hz - Alertness, concentration.
Gamma (γ)> 27 Hz - Memory and language processing, ideation.
