The five major structures of the brain are myelencephalon‚ Metencephalon‚ mesencephalon‚ diencephalon and telencephalon. The myelencephalon carries signals from the brain to the entire parts of the human body and it is also uniquely shaped looking like a little net. The Metencephalon is made up of ascending and descending tracts just like the myelencephalon. It has two major divisions which are pons and the cerebellum. The mesencephalon has two divisions also and they are the tectum and the tegmentum

Presentation Questions Ecstasy 1. Explain how the brain normally regulates serotonin. How does ecstasy act in the brain‚ & what neurotransmitters does it affect? - Normally‚ the brain regulates serotonin (5-HT) by taking up the release in neighboring neurons. - With ecstasy‚ the neuron is still supplied with 5-HT directly. However‚ ecstasy MIMICS 5-HT by blocking the reuptake of serotonin‚ [causing the release of high levels of 5-HT into the synapse]‚ which induces euphoria & the

Spinal cord injuries If the spinal cord is damaged in an accident‚ the sections below the injury will be cut off from the circuit of information to and from your brain. This means‚ all nerves - and all body parts - linked to these areas of the spinal cord will also be disconnected from your brain and will stop functioning. Well protected To minimise the risk of such an injury‚ your spinal cord is well protected: Three tough envelopes called meninges surround your spinal cord A clear fluid‚ that

Brain and Language: Importance of Brain in Language Processing Term project in the course of CS789 Special Topics in Language Acquisition‚ Evolution and Origins by SUMIT MUNDHRA under guidance of Dr. HARISH KARNICK Dr. ACHALA RAINA [Presented on 20th dec 2005] Abstract This paper deals with the studies in Neurological Basis of Language Processing. As evident from various studies done by many researchers‚ the human brain typically has some parts dealing with language processing. It is

Lobe (Neurohypophysis) – composed of nervous tissue; releases neurohormones that it receives ready-made from the hypothalamus; oxytocin and anti-diuretic hormone (ADH); released on demand in response to nerve impulses from hypothalamic neurons. Anterior Lobe (Adenohypophysis) – composed of glandular tissue; manufactures and releases its own hormones as a result of stimulation by releasing hormones from the hypothalamus; called the master endocrine gland; releases 6 hormone products which all function

cells are located in the olfactory bulbs encompassing the olfactory tract. The data then travels through the olfactory tract to the primary olfactory cortex into the limbic system. The cortex than transmits the data to three regions: the thalamus‚ orbitofrontal cortex‚ and hypothalamus. The reception of the olfactory information in the orbitofrontal cortex suggest the idea of why we perceive to smell and taste at the same time. The tongue is made up of small lumps known as papillae. Near to the papillae

The Property of Recursion in Birdsong and Human Language Introduction: Human speech and birdsong have numerous parallels. Both humans and songbirds learn their complex vocalizations early in life‚ exhibiting a strong dependence on hearing the adults they will imitate‚ as well as themselves as they practice‚ and a waning of this dependence as they mature. Innate predispositions for perceiving and learning the correct sounds exist in both groups‚ although more evidence of innate descriptions of
