The purpose of this study is to address the shortcoming in clinical hallucination research by causally manipulating the neural loci of conditioned hallucination task behavior in-person in patients with psychosis using transcranial magnetic stimulation (TMS), tracking the impact of this manipulation on the number of times participants with hallucinations report hearing tones that were not presented. With such a causal intervention, the veracity of this explanation of hallucinations will be either validated or disconfirmed. If validated, the task can be further developed as a biomarker for predicting the hallucination onset, guiding, developing or tracking the effects of treatments for hallucinations.
Hallucinations are percepts without stimulus. 70% of patients with schizophrenia suffer distressing auditory hallucinations. Their mere presence increases the risk of suicide. Most reach remission with D2 dopamine receptor blocking drugs after 1 year of adherence. However, 30% of patients have intractable hallucinations, and 50% are non-adherent to their medications, commonly because of unfavorable side-effects - those intractable and non-adherent patients continue to suffer. There is a clear need for a mechanistic understanding of hallucinations as a prelude to rational treatment design.
This study provides the initial steps towards the development of an interventional biomarker for clinical hallucinations, grounded in computational neuroscience.
Computational psychiatry involves harnessing the power of computational neuroscience to address the clinical needs of those suffering from serious mental illnesses. There has been much discussion of the promise of the approach. There have been few studies thus far and they have largely involved correlative methods like functional neuroimaging. This study will address this shortcoming by causally manipulating the neural loci of computational model parameters in-person in patients with psychosis using transcranial magnetic stimulation (TMS), tracking the impact of this manipulation on behavioral task performance . With such a causal intervention, the veracity of the model's explanation of hallucinations will be either validated or disconfirmed. If validated, the model can be further developed as a biomarker for predicting the hallucination onset, guiding, developing or tracking the effects of treatments for hallucinations. If disconfirmed, the model ought to be discarded and other alternatives should be pursued.

|---|---|---|---|
| TMS to insula | Active Comparator | This study will recruit 30 clinical voice hearers (P+H+). They will complete two parallel forms of the conditioned hallucinations task (with different visual and auditory stimuli) on two occasions, separated by a week. TMS and sham will be delivered in a randomized counterbalanced order. Hypothesis: Inhibiting the insula will decrease prior over-weighting. If this computational perturbation is responsible for conditioned hallucinations, then ameliorating it with TMS that increases insula engagement will decrease conditioned hallucination responses. Furthermore, the prior weighting parameter will be reduced following active TMS compared with sham. |
|
| TMS to cerebellum | Active Comparator | This study will recruit a further 70 clinical voice hearers. Again, they will complete parallel forms of the conditioned hallucinations task on two occasions, separated by a week. They will receive excitatory TMS over the cerebellum (and sham on the other occasion, in a randomized counterbalanced order). Hypotheses: Exciting the cerebellum will increase belief-updating. If poor belief-updating contributes to conditioned hallucinations, increasing cerebellum engagement should decrease conditioned hallucinations and alter the belief-updating model parameter compared with sham TMS. |

| Transcranial Magnetic Stimulation (TMS) | Device | Transcranial magnetic stimulation (TMS) is a noninvasive form of brain stimulation in which a changing magnetic field is used to cause electric current at a specific area of the brain through electromagnetic induction. An electric pulse generator, or stimulator, is connected to a magnetic coil, which in turn is connected to the scalp. The stimulator generates a changing electric current within the coil which induces a magnetic field; this field then causes a second inductance of inverted electric charge within the brain itself. |
| Measure | Description | Time Frame |
|---|---|---|
| Conditioned Hallucinations Task Performance | The primary outcome measure is the number of times participants report hearing tones that were not presented. There are 360 total trials. There are 120 no tone trials. People who hear voices typically report hearing tones on 30% of the no tone trials (approximately 36 times, as compared to 12 times in people who do not hear voices). The investigators anticipate fewer conditioned hallucinations (fewer than 36 reports of tones when none were presented) in the active TMS conditions as compared to the sham. | approximately 13 months |

The participant, the physician administering TMS, and the research psychologist will be blind to the condition. One research assistant will be unblinded to the condition. This unblinded research assistant is responsible for setting up the active TMS coils or the sham TMS coils and determining the protocol used, to maintain the blindness of other study staff and the participant.

| BG001 | TMS to Cerebellum | This study will recruit a further 70 clinical voice hearers. Again, they will complete parallel forms of the conditioned hallucinations task on two occasions, separated by a week. They will receive excitatory TMS over the cerebellum (and sham on the other occasion, in a randomized counterbalanced order). Hypotheses: Exciting the cerebellum will increase belief-updating. If poor belief-updating contributes to conditioned hallucinations, increasing cerebellum engagement should decrease conditioned hallucinations and alter the belief-updating model parameter compared with sham TMS. Transcranial Magnetic Stimulation (TMS): Transcranial magnetic stimulation (TMS) is a noninvasive form of brain stimulation in which a changing magnetic field is used to cause electric current at a specific area of the brain through electromagnetic induction. An electric pulse generator, or stimulator, is connected to a magnetic coil, which in turn is connected to the scalp. The stimulator generates a changing electric current within the coil which induces a magnetic field; this field then causes a second inductance of inverted electric charge within the brain itself. |
