The attention impairments in MHE are observed on a variety of measures. These include measures of cognitive processing speed involving psychomotor responding, such as the Number Connection tests (NCT), block design test (BDT),the Digit Symbol test (DST), line drawing test, circle-dotting test, serial-dotting test, figure connection test. Impairments on measures of cognitive processing speed and response inhibition that do not require a motor response have also been reported (., with verbal fluency tasks and measures such Stroop test). 22,23 Visuospatial impairments have been primarily reported on block design tasks (which also include a motor/practic component), but also on more pure measures of visuospatial perception, such as line orientation or the Hooper test. Fine motor skill impairments have been noted on measures such as the grooved pegboard task, and on line tracing tasks (the latter also involve visuospatial abilities). 24
Diet definitely influences hormonal output, and diets that lead to systemic inflammation may also lead to the upregulation of DHT at inflammatory tissue sites and thereby contribute to pattern hair thinning. But in general, I think that diet-driven hair loss from low-carb mostly comes from under-eating calories. This often results in hypothyroid symptoms, excessive shedding, cold extremities, etc. The mechanical stimulation exercises in the book, plus the dietary changes you’ve already made (getting enough calories and carbs) should help turn things around. But if not, let me know and we can continue to troubleshoot until your hair is back to where you want it.
An animal defending against a predator may engage in either " fight or flight " in response to predator attack or threat of attack, depending on its estimate of the predator's strength relative to its own. Alternative defenses include a range of antipredator adaptations , including alarm signals . An example of an alarm signal is nerol, a chemical which is found in the mandibular glands of Trigona fulviventris individuals.  Release of nerol by T. fulviventris individuals in the nest has been shown to decrease the number of individuals leaving the nest by fifty percent, as well as increasing aggressive behaviors like biting.  Alarm signals like nerol can also act as attraction signals; in T. fulviventris, individuals that have been captured by a predator may release nerol to attract nestmates, who will proceed to attack or bite the predator.
