Those who have sustained severe hippocampus damage are unable to store new "declarative" memories.
Declarative memories refer to memories that can be consciously recalled and verbally expressed, such as facts, events, or personal experiences. The hippocampus, a structure located in the brain's temporal lobe, plays a crucial role in the formation and consolidation of declarative memories. Severe damage to the hippocampus, often caused by conditions like Alzheimer's disease or certain types of brain injury, can impair the ability to create new declarative memories.
This condition is known as anterograde amnesia. Individuals with severe hippocampal damage may have intact memories from before the injury but struggle to form new memories or retain new information. Other types of memory, such as procedural memory (skills and habits) or emotional memory, which are associated with different brain regions, may remain relatively intact despite hippocampal damage.

Although dr. el-sheikh has a high systolic blood pressure, her heart rate is also high. this is most likely due to:_______
The most likely reason for Dr. El-Sheikh's high systolic blood pressure and elevated heart rate is physiological stress or an underlying medical condition.
Elevated heart rate (tachycardia) can be a physiological response to increased sympathetic nervous system activity, which often occurs during stress or in response to certain medical conditions. When the body perceives stress, the sympathetic nervous system releases stress hormones like adrenaline, which can lead to increased heart rate and blood pressure.
High systolic blood pressure, the top number in a blood pressure reading, can also be influenced by stress and other factors. Stress-induced vasoconstriction and increased cardiac output can contribute to higher systolic blood pressure.
However, it's important to note that there can be various causes for both high systolic blood pressure and elevated heart rate, including but not limited to anxiety, physical exertion, certain medications, hormonal imbalances, and underlying medical conditions like hypertension, hyperthyroidism, or cardiovascular disease. A comprehensive evaluation by a healthcare professional is necessary to determine the specific cause in Dr. El-Sheikh's case.
