For centuries, the brain has been considered a single organ from an anatomical and functional perspective. However, while the cerebral cortex, consisting of many lobes and lobules, generally creates voluntary actions, autonomous parts of the brain also carry out vital activities such as survival, reproduction, and nutrition. The functions of the group of organs that carry out basic vital activities are modulated by autonomous ganglia that work like the deep intelligence networks of the brain.

Objective: Currently, electrocautery devices have frequently been used in penile surgical procedures. We hypothesized that electrocautery using during penile surgical procedures may harm the taste rosea and the dorsal nerve of the penis or clitoris.

Methods: Eighteen young age male New Zealand rabbits were studied: five in the control (Group I, =5), five in the penile surgery without using electrocautery (sham group, Group II, =5), eight in the monopolar cautery (study group, Group III, =8) groups under general anesthesia.

Article Synopsis
  • Neurogenic pulmonary edema (NPE) is a severe complication that can arise after a subarachnoid hemorrhage (SAH), leading to high rates of illness and death.
  • This study examined the link between degeneration of the T3 dorsal root ganglion (DRG) and the occurrence of NPE in rabbits, involving 23 rabbits divided into control, sham, and study groups.
  • Results showed that greater neuronal degeneration in the T3 nerve was associated with higher NPE scores, suggesting that reducing T3 DRG degeneration could help prevent NPE and related complications.

The effect of olfactory bulb lesions on the induction time of sevoflurane has never been studied. We aimed to investigate this issue. In this study, we found that the volume of olfactory bulbs and the pore of the fila olfactoria were significantly lower with the fibrosis of olfactory bulbs in animals subjected to olfactory bulbectomy.

Background:  Life-threatening basilar artery dissection (BAD) can be seen following subarachnoid hemorrhage (SAH), but it is not clear whether SAH causes dissection, or not. This study aims to investigate the relationship between degenerative changes in the superior cervical ganglia and the dissection rate of the basilar artery.

Method:  In this study, after 3 weeks of experimental SAH, animals were decapitated.

Background:  Increased intraocular pressure (IOP) likely secondary to an activated oculo-trigeminal reflex network is an important issue following subarachnoid hemorrhage (SAH). The relationship between the IOP and trigeminal ganglion (TGG) following experimental SAH was investigated in this study.

Methods:  Twenty-three rabbits were used in this study.

Background:  Alcohol exposure may cause hydrocephalus, but the effect of vaporized nasal alcohol exposure on the choroid plexus, and ependymal cells, and the relationship between alcohol exposure and developing hydrocephalus are not well known. This subject was investigated.

Methods:  Twenty-four male (∼380 g) Wistar rats were used in this study.

Objective: The vagal, stellate, and cardiac ganglia cells changes following subarachnoid hemorrhage (SAH) may occur. This study aimed to investigate if there is any relation between vagal network/stellate ganglion and intrinsic cardiac ganglia insult following SAH.

Materials And Methods: Twenty-six rabbits were used in this study.

Background: Posterior cerebral blood flow is regulated by the basilar arteries (BAs). Vasospasm of BAs can occur after subarachnoid hemorrhage (SAH). Superior cervical sympathetic ganglia (SCG) fibers have a vasoconstrictor effect on the BA.

Scalp arteries are mainly innervated by trigeminal, facial, and vagal nerves. The ischemic neurodegeneration of the trigeminal ganglion can impede scalp circulation via vasospasm-creating effects. This study was designed to investigate whether there is any link between the vasospasm index of deep temporal arteries and ischemic neuron densities of the trigeminal ganglion after subarachnoid hemorrhage.

Study Design: Animal proof of principle study.

Objectives: To investigate neurodegeneration in rabbit L4-dorsal root ganglion (DRG) cells by creating experimental spinal subarachnoid hemorrhage (SAH), we aimed to show the neuronal pathway between L-DRG and femoral artery.

Setting: Ataturk University, Medical Faculty, Animal Laboratory, Erzurum, Turkey.

There have been thousands of neurochemical mechanism about blood glucose level regulation, but intrapancreatic taste buds and their roles in blood glucose level has not been described. We aimed to investigate if there are taste buds cored neural networks in the pancreas, and there is any relationship between blood glucose levels. This examination was done on 32 chosen rats with their glucose levels.

Objective: Parasympathetic network damage results in facial nerve damage, sublingual ganglion degeneration, sublingual gland dysfunction, and dry mouth. In this study, subarachnoid hemorrhage (SAH) was considered to be the cause of dry mouth.

Methods: We assessed 23 hybrid rabbits, including 5 control (group 1, Control).

Background: Although many theories have been established to explain the mechanism of aneurysm development following steno-occlusive or hypertensive disease, the effect of the geometrical shape of the inner elastic membrane on the maximum dilatation capacity of arteries has not been adequately investigated so far. This subject was investigated.

Methods: This study was conducted in 24 rabbits.

Anosmia has been considered as the first diagnostic criteria of Parkinson disease (PD), we investigated the effect of the olfactory bulbectomy (OBX) on histopathological features of the substantia nigra in an animal model. Twenty-seven male rats were used in this study. Animals were divided into three groups as five (control), six SHAM and sixteen study (OBL) groups.

Background: Cardiac ganglia are rechargeable batteries of the heart. The essential role of cardiac ganglia on cardiac life expectancy has not been examined following brain death. The aim of this study was to determine cardiac ganglia numbers and neuron density following subarachnoid hemorrhage (SAH).

The olfactory bulbectomy (OBX) technic is a well-known animal model for depression. According to serotonin hypothesis of depression, one of the possible explanations to this mechanism is the destroying effect of OBX on raphe nuclei which especially include serotonergic neurons. In this study, we aimed to explore histopathological findings in raphe nuclei in OBX rats.

Background: The heart is innervated by the autonomic nervous system, which contributes to the control of the heart’s rhythm and coronary circulation. It has been suggested that the cardiac fibers of the vagus nerve play important roles in controlling circulatory functions and in protecting against atherosclerotic pathologies in coronary arteries.

Aims: To investigate the presence of atherosclerotic differences in the coronary arteries of cholesterol-fed rabbits by measuring the density of cardiac ganglia neurons.
