“…Compared to conventional coils, the H‐coil contains an array of elements which are contoured to the shape of the skull, allowing deeper (up to 4.5–5.5 cm from the skull vs. 1.5 cm of the standard coils) and larger volumes of brain stimulation, affecting both cortical and subcortical regions. Promising results have been obtained by the application of deep TMS (dTMS) in reducing nicotine dependence, alcohol craving and cocaine abuse . dTMS (H‐coil) can generate an electric field which can penetrate the cortex up to 4 cm, noticeably increasing the penetration depth of the traditional TMS systems …”

Aim: To test the hypothesis that deep transcranial magnetic stimulation (dTMS) reduces food craving and causes weight loss via neuromodulation. Materials and methods:This pilot study was designed as a randomized, double-blind, sham-controlled study. A total of 33 obese people (nine men, 24 women, mean age 48.1 ± 10.6 years, body mass index [BMI] 36.9 ± 4.7 kg/m 2 ) were randomized and completed the study: 13 participants underwent a 5-week treatment with highfrequency (HF) dTMS (18 Hz; HF group), 10 were treated with low-frequency (LF) dTMS (1 Hz; LF group), and 10 were sham-treated (sham group). Food craving, and metabolic and neuro-endocrine variables were evaluated at baseline, after the 5-week treatment, and at follow-up visits (1 month, 6 months, 1 year after the end of treatment).Results: The mixed-model analysis for repeated measures showed a significant interaction of time and groups for body weight (P = 0.001) and BMI (P = 0.001), with a significant body weight (−7.83 ± 2.28 kg; P = 0.0009) and BMI (−2.83 ± 0.83, P = 0.0009) decrease in the HF versus the sham group. A decreasing trend in food craving in the HF versus the LF and sham groups (P = 0.073) was observed. A significant improvement of metabolic and physical activity variables was found (P < 0.05) in the HF group.Conclusions: We demonstrated the safety and efficacy of dTMS, in addition to physical exercise and a hypocaloric diet, in reducing body weight for up to 1 year in obese people. We hypothesize that a possible mechanism of HF dTMS treatment is modulation of the dopaminergic pathway and stimulation of physical activity.

“…In support of this idea preexisting hyperexcitability of prefrontal and ventral striatum neurons in Tmod2 mutants could actively resist the cocaine-induced depression of these regions, thereby masking the maladaptive behavioral effects of cocaine 104,105 . Interestingly, high frequency (5-20 hz) transcranial magnetic stimulation that increases cortical excitability has been shown to be an effective treatment for cocaine craving [106][107][108] , indicating that cortical excitability in naive Tmod2 KO could interfere and prevent cocaine-induced addiction behavior. Basal and cocaine-induced changes in synaptic properties of accumbens neurons are also distinct from their WT counterparts and support behavioral results.…”

Drugs of abuse induce neuroadaptations, including synaptic plasticity, that are critical for transition to addiction, and genes and pathways that regulate these neuroadaptations are potential therapeutic targets.Tropomodulin 2 (Tmod2) is an actin-regulating gene that plays an important role in synapse maturation and dendritic arborization and has been implicated in substance-abuse and intellectual disability in humans. Here we mine the KOMP2 data and find that Tmod2 knockout mice show emotionality phenotypes that are predictive of addiction. Detailed addiction phenotyping showed that Tmod2 deletion does not affect the acute locomotor response to cocaine administration. However, sensitized locomotor responses are highly attenuated in these knockouts, indicating a potential lack of necessary drug-induced plasticity. In addition, Tmod2 mutant animals do not self-administer cocaine indicating lack of hedonic responses to cocaine. Whole brain MR imaging shows differences in brain volume across multiple regions although transcriptomic experiments did not reveal perturbations in gene co-expression networks.Detailed electrophysiological characterization of Tmod2 KO neurons, showed increased spontaneous firing rate of early postnatal and adult cortical and striatal neurons. Cocaine-induced synaptic plasticity that is critical for sensitization is either missing or reciprocal in Tmod2 KO nucleus accumbens shell medium spiny neurons, providing a mechanistic explanation of the cocaine response phenotypes.Combined, these data provide compelling evidence that Tmod2 is a major regulator of plasticity in the mesolimbic system and regulates the reinforcing and addictive properties of cocaine.
