Peduncular hallucinosis is considered to be a "release" phenomenon, independent of seizure activity, although one case (McKee et al, 1990) reported the onset of hallucinations after the occurrence of a tonic-clonic convulsion.
As a "release" phenomenon, peduncular hallucinosis is in the same class of visual hallucination as hypnagogic hallucinations and those observed in sensory-deprivation states.
Complex visual hallucinations with most of the features of peduncular hallucinosis may be observed to occur in the disrupted visual fields of a significant number of patients with field cuts, the only difference perhaps being whether or not the hallucinations are limited to visual field sectors (e.g., Kolmel, 1985; Lance, 1976).

 Review of some hallucinogenic mechanism
Peduncular hallucinosis syndrome was described by different Authors as related to mesencephalic lesions; only occasionally it was connected to lesions in other zones, but always in the vertebrobasilar system circulation field.
McKee and colleagues (4) presented evidence that a lesion limited to the substantia nigra pars reticulata of the mesencephalon was sufficient to result in peduncular hallucinosis and implicated the functional relation between the pars reticulata and regulation of REM sleep.
In one case(5), the patient was fearful; in another one (6) the patient would verbally interact with her images of people when they told her about bombs that were about to drop; and again in another case (7), the patient's hallucinations were bland in colour and often perceived in fl and white.

 Peduncular hallucinosis - Wikipedia, the free encyclopedia
Peduncular hallucinosis, also known as Lhermitte's peduncular hallucinosis, is a rare neurological syndrome with a relatively rich series of detailed clinical case studies in the medical literature.
The French neurologist Jean Lhermitte in 1922 first wrote about a patient with odd visual hallucinations that were associated with suggestions of brain damage involving the midbrain and the pons.

Peduncular hallucinations are typically vivid and bright visual images of sceneries, people, animals or geometric figures.
In most cases, peduncular hallucinosis is caused by circumscribed vascular, neoplastic or other lesions in the upper brainstem (Dunn et al.
Again, disinhibition of thalamic relay cells may lead to their recruitment into resonant thalamocortical assemblies regardless of sensory input, leaving the process of perception without external restrictions and free to adopt hallucinatory forms under the direction of attentional mechanisms.

To describe the phenomenology and pathophysiology of complex visual hallucinations (CVH) in various organic states, in particular Charles Bonnet syndrome and peduncular hallucinosis.
Three cases of CVH in the setting of pontine infarction, thalamic infarction and temporoparietal epileptiform activity are presented and the available psychiatric, neurological and biological literature on the structures of the central nervous system involved in producing hallucinatory states is reviewed.
A significant degree of overlaps exists between the concepts of Charles Bonnet syndrome and peduncular hallucinosis.

The cancerous tumor in the middle of Dena Schlosser's brain and its possible effects were not part of the 37-year-old Plano woman's capital murder trial in February, which ended with a deadlocked jury and a mistrial.
Wu said it is possible the tumor created a condition known as peduncular hallucinosis, with symptoms such as vivid, recurring hallucinations, sleep disorders and problems with motor skills.
Testimony in the first trial showed that several times in the year before the killing Schlosser had religious-based hallucinations and delusions that she thought God wanted her to kill the child.
