Debate and academic research on sentience has tended to focus on mammals. Many scientists are currently divided on whether invertebrates can be classed as sentient. Thus, 30 weeks is considered a more plausible stage of fetal development at which the lower boundary for sentience could be placed. Debate around the bill has focused around the Government’s definition of an animal for the purposes of the bill, and whether this classification should extend beyond vertebrates. Before 30 weeks gestational age, EEG activity is extremely limited and somatosensory evoked potentials are immature, lacking components which correlate with information processing within the cerebral cortex. At this stage of development, however, there is little evidence for the central processing of somatosensory information. Thus, 18 to 25 weeks is considered the earliest stage at which the lower boundary of sentience could be placed. It is concluded that the basic neuronal substrate required to transmit somatosensory information develops by mid-gestation (18 to 25 weeks), however, the functional capacity of the neural circuitry is limited by the immaturity of the system. Fetal behaviour is described and the development of the underlying anatomical substrate and the chemical and electrical pathways involved in the detection, transmission, and perception of somatosensory stimuli are reviewed. For the fetus to be described as sentient, the somatosensory pathways from the periphery to the primary somatosensory region of the cerebral cortex must be established and functional. state of elementary or undifferentiated consciousness 'the crash intruded on his awareness' noun. The state or quality of being sentient possession of consciousness or sensory awareness. Feelings and emotions can be difficult to measure we can’t ask animals how they are feeling or if something hurts or. The state or quality of being sentient possession of consciousness or sensory awareness.
The answer could and should influence attitudes toward IVF and embryo experimentation, abortion, and fetal and neonatal surgery. Sentience is ‘ the quality of being able to experience feelings ’ or the ability to interpret sensations from the environment and emotions such as pleasure or pain we can also consider it as being conscious 1. Evidence from multiple scientific studies has helped us to understand that a wide range of animals are sentient beings. The question of when the human fetus develops the capacity for sentience is central to many contentious issues.
