Context: Besides emptiness, Mahayana schools often place emphasis on the notions of perfected spiritual insight (prajnaparamita) and Buddha-nature (tathagatagarbha). There are conflicting interpretations of the tathagatagarbha in Mahayana thought. The idea may be traced to Abhidharma, and ultimately to statements of the Buddha in the Nikayas. In Tibetan Buddhism, according to the Sakya school, tathagatagarbha is the inseparability of the clarity and emptiness of one's mind. In Nyingma, tathagatagarbha also generally refers to inseparability of the clarity and emptiness of one's mind. According to the Gelug school, it is the potential for sentient beings to awaken since they are empty (i.e. dependently originated). According to the Jonang school, it refers to the innate qualities of the mind that expresses themselves as omniscience etc. when adventitious obscurations are removed. The "Tathagatagarbha Sutras" are a collection of Mahayana sutras that present a unique model of Buddha-nature. Even though this collection was generally ignored in India, East Asian Buddhism provides some significance to these texts.

Question: what is the first part of the brain mentioned in the text Context: The SCN projects to a set of areas in the hypothalamus, brainstem, and midbrain that are involved in implementing sleep-wake cycles. An important component of the system is the reticular formation, a group of neuron-clusters scattered diffusely through the core of the lower brain. Reticular neurons send signals to the thalamus, which in turn sends activity-level-controlling signals to every part of the cortex. Damage to the reticular formation can produce a permanent state of coma.
